from Part I - Quantitative Data Collection Sources
Published online by Cambridge University Press: 12 December 2024
This chapter provides an overview on the use and validity of student samples in the behavioral and social sciences. In some instances, data collected from students can be of limited value or even inappropriate; however, in other cases, this approach provides useful data. I offer three general ways to evaluate the use of student samples. First, consider the research design. Descriptive studies that rely on students to draw inferences about the overall population are likely problematic. Second, statistical controls such as multivariate analyses that adjust for other factors may reduce some of the biases that may be introduced through sampling. Third, consider the theorized mechanism – a clear theoretical mechanism that does not vary based on the demographics of the sample allows us to put more faith in constrained samples. Despite these approaches, and regardless of our methods, statistics, and theoretical mechanism, we should be cautious with generalizability claims.
