I have three variables represents scores of :Test Anxiety scale, Self-Esteem scale, Academic self concept as independent interval measures. Changing exam questions answers as dependent variable (number of changing), and type of changing wrong to right, right to wrong and wrong to wrong (number of changing). my question is:
can I model these variables without indicators? or use Test Anxiety scale, Self-Esteem scale, Academic self concept as indictors for latent variable that affect Changing exam questions answers from wrong to right, right to wrong and wrong to wrong.
