Document Summary
To study one person in hope of revealing things true of everyone. Can be very revealing but sometimes the individual you study is abnormal: illusory. When participants are not given the treatment (sometimes given placebo instead) When one trait or behaviour accompanies another: control. When we think there is a relationship between two things when there isn"t. People form illusory correlations by only noticing when it relates and not when it doesn"t. Ex: couples who can"t produce children will be able to after they adopt. The experimental factor that is being manipulated; the varible whose effect is being studied. Average; adding all scores and divide by number of scores. The middle score; half the scores are above it and half are below it: mode. Measure of a relationship, measures how closely two things vary together (how one: naturalistic. Observation predicts the other) r= +0. 37 r= correlation coefficient: negative. Watching and recording the behaviour of organisms in their natural environment.
