article critique Experimental design

I’m trying to learn for my Psychology class and I’m stuck. Can you help?

It is essential you choose 2 studies that are the correct type as listed below. One two-group design and a factorial design. If the studies you choose are not those two types the paper will be a zero and everything will be of no use. If possible have both studies be about the same or similar topic.

Select a peer-reviewed, experimental research study that exemplifies a two-group design and a factorial design (use keywords method, results, and discussion in your Boolean search). These studies can be found using tools such as the GCU Library and Google Scholar.

Write a 500-750-word paper in which you:

  1. Compare the two research designs
  2. Identify the independent variable(s), dependent variable, and any possible extraneous variable
  3. Identify main effects and interactions for the factorial design
  4. Explain if the study has a random sample and/or random assignment? Were there other limitations that were noticed?
