if I have to apply true experimental design in my research study. After applying the model and passage of time can I check retention of the students through the post test which is designed for the study.
You can conduct an A-B test or the many different variations (depending on group/s). There are many models, but pay attention to variables which impact validity, reliability, and generalizability.
David Coker I'm not sure if your question was for me, but just in case: logistic regression analysis is a statistical technique for analyzing dichotomous (1/0) dependent variables.
