Document Summary

Studying behaviour scientifically ch 2: hindsight bias: you start accumulating facts to back up your position therefore biasing your opinion. You must acknowledge evidence that might contradict you. Researchers try to get around this by lying to participants about recording etc: the rule of parsimony: the simplest explantation is the best. The hypothesis with the fewest assumptions should be accepted. Handles observer bias: frequency distribution: identical mean, median and mode, mode: # that occurs most frequently, number that occurs at the peak. Standardized, a score comparable to a standardized score, so that the mean is always equal to zero and standard deviation equal to 1. ! Explanation: variable, a property whose value can change over time. An outlier score is often deleted because it will differ a mean and median, and most often doesn"t represent average behaviour: the greater the slope, the closer to 1 or -1. !
