    Correct statistical test to compare pre and post questions (dummy variable)




    Hi friends,

    What is the correct statistical test to compare a group who was tested in two points in time (pre and post) The same people.

    I have a dummy question that was asked in pre and post test (exact the same question):
    1=correct to the questions
    0=incorrect

    I want to see if there is any significant differences in participants' asnwers.

    perhaps, ttest?? it is not matter that my variable is a dichotomous.

    Thank you all in advance!

    Cheers,
    Marvin
