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! ;-)

Also, at the beginning of the write-up, please include what type of statistical test you used to analyze the data. eg. Researchers used simple regression test to explore how the numbers of car in the city affects air pollution index.
