Hi everyone,
I'm currently an undergraduate student trying to find validity and reliability of questionnaires. I have performed equivalence testing between the questionnaires for validity, test retest for reliability, and also have done Pearson correlations to identify any relationship.
I was told I should also do paired sample t tests between the different questionnaires. Although I don't understand why because this finds the significant difference when I am trying to find that the questionnaires are similar.
If anyone could help to explain this to me that'd be great!
