Hello..
Actually I get confused about the statistics analysis..
My research try to find if there is significant deference in mean scores in academic achievement between the experimental group(using flipped classroom) and the control group(using blended learning) of learning Arabic grammar .
And I have pre test and post test for each group.
when I read more paper and theses I find some of researcher using ANCOVA with considering pre test as covariate of results, and some of them using the independent sample t-test .
*My QUESTIONS Are :*
1. which analysis more appropriate for my study (independent sample t-test or ANCOVA)?
2. For measuring the normality of distribution and another assumptions do I need to check thes assumptions for pre test only or I need to measure it for post test also?
