Define independent variables - Answers :the variable that is manipulated in an
experiment
Define hypothesis - Answers :proposed explanation for an observation
Define dependent variable - Answers :The measurable effect, outcome, or response in
which the research is interested.
Define control - Answers :In an experiment, the standard that is used for comparison
Define treatment - Answers :a specific condition applied to the individuals in an
experiment
Define prediction - Answers :A logical statement about what will happen if the
hypothesis is correct.
Define experiment - Answers :the act of conducting a controlled test or investigation
Define non-experimental - Answers :observational
Define descriptive study - Answers :giving details about; illustrating; explaining
