    hi, i wanna do factor analysis in my thesis. how should the questionnaire look like, likert scale of how many options


    Okey, in term of likert scale, it is preferable to have a quasi-interval scale; at least 7 likert scale. The five likert scale is being criticizing.

    According to the items; at least for items to measure each construct after making the rotation while the sample size, there is an argue about the sample size. However, you should have at least five valid responses to each item whereas the minimum is 200 responses. see Hair (2010) Multivariate Analysis for more information.  


    Thanks Murad, I appreciate for your contribution
