2)design the experiment , experimental group and control group. Independent variable- variable that is going to be changed. Operational definition: the definition of the variable in terms of the operations the researcher performs to measure it: e(cid:454).

Single and double blind experiment, double blind is better because both subject and experimenter are aware of the value of independent variable: evaluate hypothesis, communicate results. I administer a questionnaire to high school students testing their math skills. I find that their scores are uncorrelated with those on a math iq test. I re-administer the questionnaire to students two months later and find that *their scores are relatively unchanged.
