Document Summary
Experiment: scientific tool used to measure the effect of one variable on another. Dependent variable: variable being observed by the scientist. Experimental group: is affected by independent variable (manipulation) Control group: does not get affected by independent variable (no manipulation) Confounding variable: a variable other than the independent variable that has an effect on the results. Practice effect: improved performance over the course of an experiment due to becoming more experienced. Strict selection criteria can hinder generalizability (results from very specific groups of participants cannot be generalized to other groups) The best sample is a random sample (choosing a sample at random from the entire population) Placebo effect: effect that occurs when an individual exhibits a response to a treatment that has no related therapeutic effect. Test improvement may be due to a participant"s influence, not the experimental manipulation. Participant bias: when a participant"s actions is an experiment influence the results outside of the manipulations of the experimenter.
