Next, briefly discuss how understanding each term individually in addition to how these terms interconnect is important for your understanding of the application of research designs. 2. Discuss the importance of validity and research design. Next, choose one type of validity (internal, external, construct, or statistical conclusion) and discuss its relevance to experimental, quasiexperimental, and nonexperimental research. Exercise 1. Define a sampling strategy. 2. Define the two major types of sampling strategies .
Some researchers recommend using this technique when N < 100 (Lachin, Matts, & Wei, 1988). 18 + AN APPLIED GUIDE TO RESEARCH DESIGNS + COMPARISON AND CONTROL GROUPS The group that does not receive the actual treatment, or intervention, is typically designated as the control group.

SPSS) refer to the IV differently. For instance, the IV for the analysis of variance CANOVA)in SPSS is the "breakdown" variable and is called a factor. , the treatment group is Level 1, and the control group is Level 2). For nonexperimental research that uses regression analysis, the IV is referred to as the predictor variable. In research that applies control in the form of statistical procedures to variables that were not or cannot be manipulated, the IVs are sometimes referred to as quasi- or alternate independent variables.
