Document Summary

Belief that leads to its own fulfillment. You are conveying your expectations in hints and subtle gestures in which the subject begins to fulfill your expectations. To avoid this, you can conduct double blind study, avoid times you spend with the subject i. e instructing them through a computer to reduce face-face contact. One way to reduce experimenter bias is to have a double blind study. In other words, the subject is blind to the study, but the researcher who is interacting with the subjects are blind as well, the person who knows the variables is not going to be the experimenter. Mathematical computations that summarize and organize data. 2 types: descriptive statistics describe the characteristics of your data. Real = true of the population = statistically significant. How much your scores spread from your mean: range lowest highest, standard deviation measures the average spread of scores (deviation) from the mean.
