If I want to use this design, can I use a paired t-test to compare the pre-test and post-test results of the experimental group that received both a control and independent variable to see if both variables together improved their performance while also conducting an independent t-test on ...
A one-group pretest-posttest design is a type of experimental design in which a single group of participants is measured before and after an intervention or treatment. It is often used when it is not feasible or ethical to have a control group. Here is a step-by-step breakdown of a one...
Pretest-posttest designsare an expansion of the posttest only design with nonequivalent groups, one of the simplest methods oftestingthe effectiveness of an intervention. In this design, which uses two groups, one group is given the treatment and the results are gathered at the end. Thecontrol...
The pretestposttest design is widely used to investigate the effect of an experimental treatment in biomedical research. The treatment effect may be assessed using analysis of variance (ANOVA) or analysis of covariance (ANCOVA). The normality assumption for parametric ANOVA and ANCOVA may be ...
