    Is Paired T-test the right tool to use?




    Hi!

    I want to know whether the paired t-test can be used when the variables for comparison are different (but measuring similar constructs and on the same scale), i.e., it's not the common before-/after- measures of the same DV on the same sample usually used

    For example, if in one survey, I asked the following two questions and both are measured on a 5-point scale:
    (1) How likely are people to click on ads shared by friends? (M = 3.8)
    (2) How likely are people to click on ads shared by companies? (M = 2.5)

    How can I test if the mean of the first question is significantly higher than the mean of the second question? Is paired t-test the right way to go for? If not, what is the right tool I should use then? Thanks in advance!

    Yep, a t-test seems fine here. (Well assuming the distributional assumptions are met and so forth).
