According to Yegidis (2012, p. 120), a research design is "a plan to attempt to find answers to the researcher's questions and/or to test any hypotheses that were formulated." There are several different types of research designs. Each design is intended to respond to a particular type of research question. The type of research design depends on the type of research questions asked. For this Discussion, select one of the articles from the reading list and consider several classifications of group research designs.

Post by Day 3 your response to the following: Describe which groups are compared in the research. Then, classify the research design as follows:

1. By explaining whether the study is pre-experimental (cross-sectional, one-shot case study, and longitudinal), experimental (control group with pretest and posttest, posttest only, or four-group design), or quasi-experimental (comparing one group to itself at different times or comparing two different groups)
2. By indicating what the researchers report about limitations of the study
3. By explaining concerns you have regarding internal validity and the ability of the study to draw conclusions about causality
4. By explaining any concerns you have about the generalizability of the study (external validity) and what aspect of the research design might limit generalizability
