Demand Characteristics

Features of an experiment that communicate to the participant the experimenter’s hypothesis.

Margin Of Error

A statistic measure of the amount of random sampling error in a survey’s results—for example, a 3% margin of error means that the survey’s result could be 3% lower or 3% higher than the average response—the larger the sample is, the smaller the margin of error is.

Measurement Validity

The extent to which a tool, test, or instrument accurately measures what it is intended to measure.
