how to make t_test on a questionary
We showed a video to 40 participants and then asked them to fill a questionnaire of 25 questions.
Then we shoewed another video and aske them to fill the same questionnaire for second time.
Now we want to check which video preferred better regard to answers to the questions in questionnaire. We choosed anova and T_test to figure it out.
To this end we defined each question as a variable, so in spss we have 25 rows and 40 culomns. Then from: analyse--- compare means, we choosed independent t_test.
The output is a table of 25 rows and for each row (i.e. each question) we have t value and p value,
In next step we have to compare the t test/anova results of first video and second video. is it true to show them by a chart bar? thanks in advance
