I have some items to measure students' beliefs about the effects of their teachers' traits on their classroom participation. For example, I asked my participants to rate on a 5-point scale to what extent they agree with the following statements

1 I feel nervous in the class because my teacher is strict

1=strongly disagree 2=disagree 3=undecided 4=agree 5=strongly agree

2 I feel relax when my teacher responds in a friendly way.

1=strongly disagree 2=disagree 3=undecided 4=agree 5=stronly agree

I am just wondering if I need to reverse code the second item?

I ran three one-way ANOVAs, one for each of the tests. All obeyed Mauchly's test of sphericity, and all returned non significant results, indicating that the null hypotheses cannot be rejected.

My university's notes are unclear as to how to proceed. Do I just say "Well, results were not significantly different for each test after exposure to each warm up protocol, here's why I think that may be" or do I look for more subtle trends in the data? Is there any post-hoc work to be done at all?

Thanks

P.S. was using 3 separate one-way ANOVAs even appropriate? ]]>

I am trying to run a test with 1 dependent variable and 1 independent variable. I also have three other 'control variables' for which I need to test whether there is an effect on the dependent variable. Which test should I use in Stata?

Second question: I have my data in an excell spreadsheet. The rows contain the variable names and the columns the data input. The variables are as follows: Stock value (absolute value), compliance (a percentage), total assets (absolute values), leverage (a percentage) and industry type (a number from 1-8 determining the different types of industry). I have data for 22 companies which are listed in the first column in excel. Another tricky part is that for each company and each variable I have data for 4 different years. I am wondering how I can get all this into stata and how I should run the analysis. I'm thinking multivariate regression is in order? But I do not know how to run this test and I am not sure how to do the test since I am using multiple years. Should I run a multivariate regression for each of the 4 years seperately?

Thank you kindly. ]]>
