Abstract

Psychological research can be broadly classified into experimental or non-experimental. In experimental research, independent variable is manipulated to see its impact on some variable of interest. On the other hand, in non-experimental research, existing association is used to study the cause-and-effect relationship. A detailed discussion has been made in this chapter on various considerations in developing an empirical study. To ensure internal validity, one needs to maximize the systematic variance, control extraneous variance, and minimize the error variance. This has been discussed by means of an illustration. After going through this chapter, the readers can understand different methods of psychological research and use appropriate research designs so that the internal validity of findings can be enhanced. To control the variability in sample, blocking principle has been discussed in detail. Further, the readers will also understand the situation where the factorial experiment can be planned.
