LING 333 Chapter Notes - Chapter 7: Internal Validity, Repeated Measures Design, Second Language
Document Summary
In this chapter, we provide an overview of experimental design options available to linguistics researchers, as well as a brief overview of mixed methods, an increasingly common option for investigating complex research questions: fundamentals. Researchers adopting a quantitative approach seek to investigate phenomena by collecting numerical data and analyzing those data statistically. If an experimental approach is adopted for example, observations or measurements to be collected under relatively controlled conditions. Asking and answering these questions is important for ensuring three general desiderata of quantitative research in any discipline: reliability, and replicability. That is, if a study possesses external validity, the results should hold true not only for the participants in the study, but for a larger population as well. Measurement, both by different raters and by different instruments (instrument reliability) ^^^^ refers to a study that can be repeated w/ other subject populations and in other contexts. A study that can"t be replicated should be treated cautiously by the field.
