My apologies for intruding on your class blog, but it was the best way I could think of to contact you without adding to your email spam filter!
I just wanted to say thank you for the bagels the first year class provided for faculty and staff earlier this week. I also wanted to thank you for your attendance and participation at the community meeting. Both the bagels and the engagement were tremendously appreciated.

Table HELP!
If the correlation between two different values is 1.0, (ie. height in inches and height in feet), do we actually put a 1.00 into the table, or put the dash?
Please read wed night!
Sorry, but after I took the bold off of the top line as you said, the line isn't connected...it's the little dash marks w/that tiny space in between. Also, I cannot get the extra line after the title to go away. I clicked double space and tried to erase the extra line with no luck.
thanks!
Nikki

Confidence Interval (CI)
Someone from the class asked about confidence interval...
In order to understand confidence interval, you have to understand standard error first. When you run a simple/linear regression test on SPSS, one of the output table should contains standard error for your regression model. You will also see that the standard error falls under "unstandardized coefficients", which means that it is an unstandardized value.
Standard error (SE) is pretty much a self-explanatory term... obvious, it has something to do with error. Do you still remember the error that we are talking about in research model? So, whenever you have to infer your test analyzes results to the population, you need to count in the error because you're using sample in your research study rather than the whole population. SE is what you want to add or subtract from the predicted score (y variable). As regression is trying to find out whether the x variable predicts the y variable or not, you can try to guess what score you will get for the y variable by providing a score for the x variable. When you want to predict the y variable to the population, you have to add or subtract the SE from the predicted score to a range of score for the possible score of y in the population.
Let's get back to CI, APA publication manual strongly recommends us to report the 95% CI for any inferential statistics. When you say 95%CI, that means you are sure that 95% of the time you predicted score for the y variable falls within the CI. For example, let's say your SE is 1.50, and the predicted y value is 100. For 95%CI, you're sure that 95 out of 100 guesses you will get a score between 98.50 (100-1.50) and 101.5 (100+1.50) for your y variale in the population.
I hope the explanation of CI help you get through the homework.

Good Plagiarism Q
This was in a comment, and I want to bring it out to the main blog because i have a feeling people aren't checking the comment sections. Christie asked:
"I am scared to plagarize. there is only so many ways you can say variable 1 and variable 2 are correlated. i dont want to get in trouble for saying something clearly, which happens to be the same way someone else did too. . . tips?"
You just now did a paraphrase Christie! I didn't write anything about correlation on mine. But, if you want more examples, that will come with reading articles. The more you read, the more you'll get the gist of your own style, because you'll have a deeper concept. That's probably the best thing i can tell you. actually, i asked the same thing last year...it's posted a ways down the blog, and Mari gave us good advice::
"I would strongly recommend that you read all the examples ...Read them carefully, understand how they are written, and then put them aside. Write your own write up, and do not consult the examples while you are writing. If necessary, refer back to the examples after you are finished writing to check and see that you included all important information. Don't actually look at the examples while you are writing, though, because that makes not plagiarizing very, very difficult."
Hope that helps!

APA Write ups! (Renewed)
Hello All. So, we finally have some clarification about what to include in the write-up and where!
A sample write up (although one I am presently making up as I go) will look as follows:
A linear regression was used to test the hypothesis that time in minutes would predict understanding. The overall model proved significant in that R = .97, F(1, 222) = 579.32, p < .001. As time in minutes increased, understanding also increased (B = 125.23, SEB = 0.25, β = .97, p < .001, 95% CI [123.23, 127.23]).
Until we find otherwise, we are going to report the CI with the coefficients that it relates to (the Betas) and NOT with the R statistics (like in the example given from page 117 of the APA manual), mainly because that is where SPSS is pulling the CI from, so that is how we would report it. PLEASE NOTE! You still need to report the proper statistics from the coefficient table, the 6th edition DID NOT take those away!!! Also...this is not the only way you can write a write up, make sure you are not plagiarizing the examples that any of us have given you! Mainly, just make sure that you include all the necessary elements of the write up and from there the style will come!
Hope this helps! Thanks for your patience as we figured this out!

Answers for unanswered question from Monday Review Session last week
During the Monday Review Session last week, several questions were unanswered, but here are the answers.
1. What does F ratio tell you? What does it have to do with regression?
- F ratio tells you how big the explained variance and unexplained variance
- F ratio determines whether your regression model (in the case of regression) is significantly different from the null model (zero) or not
- the significance level tells you whether your regression model is significantly different from zero or not
2. What does d.f.s. mean in lecture 6 powperpoint slide 27?
- d.f.s = degress of freedoms
- referring to slide 26 ANOVA table (SPSS output), df for "total" is equal to the sum of df for "regression" and df for "residual"
3. Do I have to know assumptions of regression now (see lecture 6 powerpoint slide 18)?
- no, don't worry about it if you don't understand it now. Sung will revisit this topic with a lecture later on in the course.

Homework 2 help
Some people from your class asked about how to report statistical results in APA style, here is a sample that you can follow, but you need to paraphrase it in order to use it in your homework.
To report your model is significant or not (for all kinds of regression):
Significant relationship between number of cars and air pollution index was found, that the number of cars can predict air pollution index, R2 = .88, F(1, 33) = 236.32, p < .001, 95% CI [.02, .22].
To report the direction of your model (for simple regression only):
Increasing the number of cars was related to more severe air pollution, B = 3.87, SEB = 0.25, β = .94, p < .001.
As always, it is worthwhile to look up APA Publication Manual (6th ed.) because it provides critical information on how to do a write-up correctly for your homework. :)
Good luck! ;-)

A word on early Article Reviews
Here's the deal. You can turn in your article review early like Dr. Kim said. We your TA's will look over ONE and return it to you with marks but NO GRADE WILL BE ENTERED. All required article reviews will still need to be turned in by the normal dead line. This means if you have an early review returned to you, YOU MUST TURN IT IN AGAIN to receive credit. Also, if you have turned in more than one article for early review only one will be reviewed but both will be returned to you so you can make corrections on both. If you have turned in two different types of articles we will still only "test grade" one. Sorry if this disappoints, we have to draw a line somewhere =). Most of the issues that people will have relate to formatting and are more or less the same for both types of reviews.
Thanks!

Single space is recommended.
Yes, I know. Double space is the standard. However, we want to save trees. Thanks.
You can submit your very first article review for a check and get it back with no grade or no penalty, if you want to. However, you need to submit it soon because TAs will be inundated with many article reviews as the first deadline (first 4 article reviews by either Nov. 2nd or 3rd) is approaching. Please note that TAs will be reading about 150 article reviews in early November.

article review questions..again.
I know that the new edition of the APA manual says we have to double space everything. Is that true for our reference list? Do we double space after each period?

Another Article Review Question
I was asked:
"do we have to include a copy of the article with our review? And, how do you tell the difference between an empirical article and the other one"
(a) No, you do not have to include a copy of the article. If we need something, that's what the reference is also used for, you're most likely getting it on EBSCO, so if we need it we will be able to search for it on EBSCO.
(b) My fellow TAs and/or Sung can add to this second part if they think of better clarifications. I think that The best way is to see whether or not there were any tests run. If you see numbers, it is most likely empirical. If you see any statistics, this is most likely empirical. Theory-based articles will just base off of theory, and so when you read through it and write the review you'll use those other headings found on the second page of the example to clarify (i.e., Reference, Major Premise, Development of the Argument, Population From Which the Theory was Developed, Strengths and Limitations of the Paper, Relevance for the Current Question)
Hope this helps...other TAs and Sung may help more.

Article Review
Your pseudonym or real name goes to the "Strudel...." You can use the same pseudonym that was used for your homework. If you want to use a different pseudonym, please let me know.
You should follow the 6th edition. I strongly recommend you have a personal copy of the APA Publication Manual (6th ed.). You can buy one at the Fuller Bookstore. Today (Monday) I had a brief review session on article review with the Monday class and am going to have another one with the Tuesday class. If you are familiar with the 5th edition, you need to educate yourself with the difference between the 6th and the 5th editions. Please visit the following website for a brief review on that (Thank you so much, Grace!).

Hey Grace,
So we just put our pseudonym, but then what? For the sample, it has Toaster Strudel, Sandwich, Spaghetti...do we need to type three things there or just our pseudonym?
Also, do we need to inlcude the doi in listing our reference? I have the newest edition of the APA manual, and I'm unclear if I need to provide another number. I've retreived most of my articles from the library's online databases.
Thanks!

Okay I'll admit it...
On the quiz I could not remember how to calculate IQR. Can you review the equation? ~Amber B.
Article Reviews
Just to clarify (again), our article review should be one page, single spaced and follow the example for the section titles?
Also, at the top of the sample review, it has "toaster Strudel, Sandwich, Spaghetti". What goes there? Is that we're are pseudonyms go?
Thanks!

Hi TA's,
Let me know if this isn't true, but I think I remember hearing you guys say that you are willing to look at our first Article Reviews to make sure we did them correctly before we turned them in.
Yes? No? Maybe? :)
Thanks for all your help so far!

question about review slides
It may be a bit late, but I noticed a discrepancy between the review notes (slide 6) and the lecture notes (lecture 2, slide 14). The lecture slides say that the saturated model has no explanatory power but the review slides say that the saturated model has the highest explanatory power.
Just wanted to point that out. My feeling is that the lecture notes are correct though I may be wrong.

Review Follow-up
Hello All!
I officially posted the slides I used in the review last night (Monday) onto Portico. Feel free to access them.
HOWEVER please note the disclaimer! These are just a simple review! Although they are taken directly from Sung's lecture notes, they are only supposed to supplement all of his lecture powerpoints! Just because something is included in the review powerpoint does not mean it will definitely be on the test. Also, just because something was excluded from the powerpoint, does not mean it will be excluded from the test. Study wisely!
If you have questions, feel free to blog them or email for us to blog! Also, the Wednesday review session will most likely cover these powerpoint review slides as well for those who missed the Monday review.
Hope it helps!

Boxplot Question
This question just in...
"Can someone tell me how to create the box and whiskers plot."
Do the following...
Graphs --> Legacy Dialogs --> (Boxplot) --> (make sure to select simple boxplot AND "summaries of separate variables") --> (click over desired variable) --> OK
That should do the trick.
Sorry the "summaries of separate variables" was not in the original explanation.
Hope that helps =)

HW #3 Z-score calculation
I want you to calculate the Z-scores of the values (16, 18, 20, ...) using the means and standard deviations of x and y. The values (16, 18, 20, ...) has nothing to do with the ids (representing rows) of the homework data set. If you have any questions, please let me know. Thanks.

Weekly Review Session Time and Venue
Hi everyone,
Starting from next week, we (TAs) are offering two review sessions every week. Here are the times and venues.
1. Monday 5:30pm (Payton 100)
2. Wednesday 6pm (Psych. Building 120)
We will make these review sessions to quiz review sessions when quiz is around the corner. Otherwise, we will normally just go over some difficult parts of the lecture or answer whatever questions you bring to the review sessions. If you have any questions on your homework, please feel free to blog your questions here, we'll try to get back to you asap. Have a good weekend!

Saving Trees
There were a few of you interested in turning article reviews electronically. Dr. Kim will have to make the final call on this one but for now plan on printing them out and turning them in hard copy. Using pseudonym's might make it hard to do it on line. That and there's enough new technology to figure out for this class already, working with one of the electronic services at this point would probably get in the way of the course content.

Correlation and Covariance
We just realized that we did not include commands for finding correlation and covariance in SPSS. Here they are...
Finding corretation and covariance,
Analyze ---> Correlate--> Bivariate --> Select Variables --> Options --> New Window pops up --> select "cross-product deviations and covariances -->OK -->OK
For the scatter plot,
Graphs --> Legacy Dialogue --> Scatter plot --> select variables to "x-axis" and "y-axis" --> OK
To add line of best fit,
double click on scatter plot on the output window, click the left fifth icon on the bottom tool bar, make sure it's on "linear" mode". The line of best fit should be on the scatter plot after clicking the icon.
Hope this helps!

General question about the homework
Dr. Kim told us to attach work on the homework, but I wasn't quite sure whether he only wanted the graphs or also the way I calculated the z-score.
Clarifying points
YES, there WILL be a review session this Monday October 12 at 5:30 but the location has not been determined yet. Sung is searching for a room for us.
Also, as a follow-up about the article reviews. If you prefer to get our feedback from one before you do them all, feel free to test it out and we'll grade it and get it back so you hopefully won't make the same mistakes on the rest of them. Personally, I highly suggest trying to do one early so that you get the feel for it and also get the rubric down. (And it will take some of the load of the end of your quarter, which i know is quite bulky!)
Hope all is well! Hopefully see you tomorrow (friday) for the spss review!

Article Review
Hi,
Let me clarify about article reviews. If there is anything confusing, please refer to the sample article review. For example, I am going to explain later in the class, but for now b (analyses listed) & c (findings described) in the syllabus should be combined into b (findings) in the sample. Also, d (sample described) in the syllabus is equal to c (population) of the sample.
If you have any questions, please let me know. Thanks.

Questions about Journal Articles
Hi TAs,
Thank you for the info about review sessions!
I have a few questions about the journal articles:
1. The sample article review posted on portico appears to be single spaced and is about 1 page in length, but APA formatting is often double spaced and Dr. Kim noted in class the article reviews should be 2 or 3 pages. Could you confirm spacing and length requirements for article reviews?
2. The sample article review posted contains 5 italicized "substantive components" (hypothesis, major findings, population, etc) and the syllabus contains 6 components - the additional one is "analyses listed." Should this analyses section also be included and if so, what info should it contain?
Thank you!
Melissa

Article Review
Someone from this class asked about article review...
Here are some tips...
Here are some tips...
- Dr. Kim has posted an example of article review on portico which you can refer to
- Make sure you include all the headings that are on the example. You can choose to copy the headings from the example (with exact wording, we won't count it as plagiarism). Of course, you're welcome to paraphrase them if you find some better ways to say them.
- Make sure you are following the APA Style Manual in terms of citation and writing style because you will get points off if you did not follow it. For example, never start a sentence with a number (eg. 50), but spell it out (Fifty). Also, make sure you have 1 inch for all margins. You can find APA Style Manual in the Hubbard Library or Integration Library (on reserve) if you don't own one. Here is a helpful website on APA style: http://www.docstyles.com/apacrib.htm
- For any information that the authors should have included in certain sections of the article, make sure you point it out under the section "Flaws of Study and Limitations to Generalizability". For population, you have to include number of participants, gender, enthicity, and age. For example, if the researchers forgot to include the age of participants, make sure you report it.
- Try your best to keep your article review in a page, it's okay if you really need to go over a page
- Make sure you will use quotation marks and include page number(s) if you are quoting something from the article; otherwise, paraphrase everything else.
- Some of you might have learn to put 2 spaces after a period, there is only 1 space between a period and the beginning of a sentence.
- This homework is help you to build up your literature review if you have decided what you want to do for your master/dissertation. If you don't have an area of interest, no worries, you can take this opportunity to explore your interests. So, try to stick with what you are really interested in and demonstrate it under "Relevance for the Current Question"
- In the "reference" section, make sure where to put a space, some periods after authors' initials are followed by a space, some are not. Also, know when to capitalize and when not to, especially for the title of the article.
- You don't need a cover/title page for this homework, use the same layout in the example
- Under "Major Findings" section, you do not need to report descriptive or inferential statistics, rather, you just need to report what kind of test analyzes the researchers used and summarize the findings.
- If you are doing the article review on a qualitative study, follow the headings that are listed on the second page of the example article review posted on portico.
**Review Sessions!!**
HELLO ALL!
So! After great consideration and hearing your response to review sessions, we have decided on a few things.
First of all, we would like to host a SPECIAL review session to intro SPSS and answer any SPSS and/or first homework related questions. This will be THIS Friday, October 9, 2009 at 1:00 pm in the research computer lab in the library. But if you could, come EARLY (5-10 minutes) because the Lab we are in has a login that the tech guy will need to help us with. If you're wondering where the lab is, the front desk should know.
FYI, Grace and I will be using a sample data set that is different from your homework, but are willing to answer any questions regarding the homework and how it works out on SPSS. You will just have to go back and use your own dataset when completing the homework.
Ok, on to the NORMAL/WEEKLY review sessions. We have decided that Monday at 5:30pm (in a location to be announced soon) and Wednesday at 6:00pm (in the psych building room 120) are going to be the normal sessions. I think there are about 4 or 5 of you that this may not work with, and that is fine, if you want a review session FEEL FREE to set one up with one of us, we all enjoy doing this and would be able to better cater to your individual needs.
I hope that this helps out as you expect. If there are any suggestions that any of you may have, feel free to blog it or email one of us for us to blog.
p.s. don't miss the great info about SPSS info in the post just before this one...it gives exact ways to compute with SPSS that will help before the review!

SPSS HELP E-mail
Hey Everyone,
This is coming to you both on the Blog and via e-mail. Future things will all be posted on the blog but until we're all on the blog there will be a few more mass e-mails. Sorry for the inbox clutter.
We are working to put together a review session specifically for SPSS intro on Friday. Location will be the classroom in the library (ask at the library front desk). Time TBA.
We will be focusing on what you need to know to do the homework, class notes will be discussed NEXT week at the normal review sessions. However, we only know SPSS and any questions on how to use "R" need to be directed to Dr. Kim. Please bring your questions to review or post them to the blog if you can. If you can't make the review or aren't able to work the blog yet feel free to e-mail one of us and we'll do everything we can short of doing it for you =). We will be working from an example data set on Friday that does not match the homework assignment.
In case you don't / can't come here's a play by play on how to use SPSS...
The following is taken from Dr. Mari Clements notes with permission...
To obtain estimates of central tendency... ( 3 different ways)
After loading data set into SPSS...
Click on Analyze (one of the options in the top toolbar)
Then select... Descriptive Statistics --> Descriptives --> (click over variables of interest) --> Options --> (check desired stats) --> Continue --> OK
Click on Analyze (one of the options in the top toolbar)
Then select... Descriptive Statistics --> Frequencies --> (click over variables of interest) --> Statistics --> (check desired stats) --> Continue --> OK
Click on Analyze (one of the options in the top toolbar)
Then select... Descriptive Statistics --> Explore --> Dependent List --> (click over variables of interest) --> OK
For Interquartile range: Follow the above directions.
For the graphs/charts you need...
Graphs --> Legacy Dialogs --> (Select desired plots) --> (If necessary, specify type, e.g. simple boxplot) --> (click over desired variable) --> OK
Analyze --> Descriptive Statistics --> Frequencies --> (click over variables of interest) --> Charts --> (check desired stats) --> Continue --> OK
Analyze --> Descriptive Statistics --> Explore --> Dependent List --> (Click over variables of interest) --> Plots --> (Check desired plots) --> Continue --> OK
For Creation of histograms with normal curve imposed:
Analyze --> Descriptive Statistics --> Frequencies --> (click over variables of interest) --> Charts --> Histogram (select "with normal curve") --> continue --> OK
*** you will need to select "simple boxplot" in order to make the required boxplot chart
To make "Z-scores" with SPSS (you can calculate these by hand)
Analyze --> Descriptive statistics --> Descriptives --> (Click over varibles of interest) (select "save standardized values as variables --> OK
We hope that makes sense. Please e-mail or blog any questions. You can also bring your questions to review on friday.
