Document Summary

Summarize and describes the characteristics of a set (distribution) of scores: construct a frequency distribution: how many participants got each score, convert into histogram: graph of frequency distribution (column or bar graph)- shows how frequently the score occurred. Describes a distribution in terms of a single statistic that is typical of the whole sample: mode: Add all the scores and divide it by the number of scores provided: median: Point that divides the distribution in half when the scores are arranged from lowest to highest. Half of the scores above it, half below it- middle point. Information about the spread of scores in a distribution: range: Highest score minus lowest score: squared deviation: Square the deviation (no minus signs: variance: The mean of the squared deviation scores: standard deviation: R can be between -1. 0 and +1. 0. Direction means that one variable increases while the other decreases. Actions and responses that we can directly observe, requires critical thinking.
