Does Intrinsic vs. Extrinsic Motivation Play a Role in People who Exercise Alone or With a Partner?
The independent variable for this experiment is whether they exercise with a partner or not. The dependent variable is whether the person is intrinsically vs. extrinsically motivated to exercise. Participants filled out The Behavioural Regulation in Exercise Questionnaire (BREQ-2).
Subscales to the questionnaire include amotivation, external regular, introjected regulation, identified regulation, and intrinsic regulation. The questionnaire uses Likert-type item questions. The website for the questionnaire said to calculate the means for each subscale, which I already did but don't know where to go from there.
I calculated the means as follows:
Amotivation 5 9 12 19
External regulation 1 6 11 16
Introjected regulation 2 7 13
Identified regulation 3 8 14 17
Intrinsic regulation 4 10 15 18
I am not so sure if I do understand what you wanna test but to me it sounds like Chi-square Tests of Independence (Chi-square Tests for Two-Way Tables). Does this make sense? check out https://www.youtube.com/watch?v=L1QPBGoDmT0
Let's wait for more answers to your question before you completely trust my guess...maybe the video helps.
Cheers
If you only want to look at the relationship between whether or not they exercise with a partner (a binary, categorical variable) and whether they are internally or externally motivated (another binary, categorical variable) then chi-squared is enough. If you also want to see how much all the other survey results predict the dependent variable, you should use logistic regression, which will allow you to analyze all those independent variables together.
I agree with the above comments. Chi square requires counts so you will have to decide what value is considered "identified regulation" or not and so on. Once you have the counts for each category you would construct a chi square where the column would be partner/no partner then the rows would be the various Likert items.
Alternatively you could use one of the suggested tests in the following article - perhaps ordinal logistic regression...
