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 ...

Why is pretest-posttest design referred to as quasi-experimental? Study participants were not randomly assigned Study participants are asked to provide feedback on the study design Study participants are assigned to control group The effects on participants are not monitored carefully ...

Design 1 is still predominantly used in studies with pretest-posttest data. When the groups are relatively large, for example, one can randomly split the exper- imental group into two groups and the control group into two groups to use the Solomon four-group RD. ...
whereas the control group is given none, and this allows the researchers to determine if the drug really works. This type of design, whilst commonly using two groups, can be slightly more complex. For example, if different dosages of a medicine are tested, the design can be based around ...
What is a one-group, post-test only design? Twenty students randomly assigned to an experimental group receive an instructional program; 30 in a control group do not. After 6 months, both groups are tested on their knowledge. The experimental group has...
This study compared two formats of a social story targeting the improvement of social skills during game play using a pretest posttest repeated measures randomized control group design. A total of 45 children diagnosed with Autism Spectrum Disorder (ASD) ages 7-14 were randomly assigned to ...
