Generalizability is applied by researchers in an academic setting. It can be defined as the. extension of research findings and conclusions from a study conducted on a sample. population to the population at large. While the dependability of this extension is not. absolute, it is statistically probable.
Comparing them in cross-case analyses is a way to enhance the external validity or generalizability of their findings. Three phases were used in this survey to insure scientific validity and generalizability of the results. generalizability of small-scale studies, validity) by attendees of the 2008 AERA.
