How to compare data from two single case studies

Question

Hey guys!

I am currently looking to compare questionnaire data from two single case studies (from a total of two people). How can I do this?

The questionnaire includes Likert scale questions and multiple-choice questions.

thank you so much… it's my first time doing this and i have no idea what im doing

Answer 1

You might be able to make some very basic observations, such as which of the two people scored higher in certain questions, but a sample of two people is far too small to perform any of the statistical tests people normally use for questionnaires answers, such as regression, t-tests or ANOVA.

Answer 2

T - test analysis is usually fine for comparing 2 groups.
