Fundamentals Of Experimental Design Pogil Best

Reliability refers to the consistency of results. If an experiment is performed multiple times, does it yield the same data? This is achieved through multiple trials or large sample sizes. POGIL exercises often prompt students to look at data sets with high variance to realize that a single trial is never enough to draw a conclusion.

Independent Variable: This is the factor that the researcher intentionally changes. It is the "cause" in a cause-and-effect relationship. In a POGIL activity, you might identify this by looking for the one element that differs between experimental setups. fundamentals of experimental design pogil

Example from the POGIL: Testing fertilizer on plant height. Reliability refers to the consistency of results
