According to Shaughnessy, Zechmeister, and Zechmeister, 2009, “in applied behavior analysis, methods developed in the experimental analysis of behavior are applied to problems socially relevant (Shaughnessy, Zechmeister and Zechmeister, 2009, p. 317). In this article, I will discuss some of these experimental methods used in applied research. First, I will discuss the similarities and differences between descriptive and inferential statistics, as well as when they should be used. Additionally, I will explain the similarities and differences between single-case and small-N research designs. Additionally, I will explain when single-case and small-N research designs are used. Moreover; I will look at real experiments and examine how they control for threats to internal validity. Additionally, I will examine how actual experiments differ from experimental designs. Finally, in this article, I will discuss quasi-experiments by explaining their importance and how they differ from experimental designs. According to Shaughnessy, Zechmeister, and Zechmeister (2009), data analysis and statistics play a major role in analysis and interpretation. of experimental results. Descriptive statistics and inferential statistics are both used to describe the results of an experiment. In addition, they make it possible to confirm that an independent variable has an effect on behavior. Additionally, descriptive statistics and inferential statistics are used in the data analysis stages of an experiment. Additionally, descriptive statistics are used in inferential statistics (Shaughnessy, Zechmeister & Zechmeister, 2009). There are differences between descriptive statistics and inferential statistics. For example, descriptive statistics are used to help...... in the middle of an article...... and how they control the internal validity of an experiment and how they differ from experimental designs. Finally, I discussed quasi-experiments by discussing their importance and examining how they differ from experimental designs.ReferencesWorks CitedAeschleman, Stanley, R. (1991).
