Hello all UX researchers, In my recent UX study, I used a single ease of use question at the start and end of the each task on the scale of 1 to 7 ( where 1= strongly disagree, 7= strongly agree).
Pre-task question: The participants were asked to rate how easy/difficult they thought the task was going to be.
Post task question: The participants were asked to rate how easy/difficult the task actually was.
I am interested in learning about your process of analyzing such data.
Q1. Do you perform descriptive statistics on all scores or select only the ratings of the participants who completed the task successfully.
Q2. I normally plot pre/post data and perform paired t-test. What is your process?
Thank you for response.
