Document Summary

Frequency distribution: common procedure for organizing a set of data (descriptive statistics) Organized tabulation of the number of individuals located in each category on the scale of measurement. Allows you to see the location of any score relative to all the other scores in the set. Can be structured as a table or graph: set of categories that make up the original measurement scale, record of the frequency, or number in each category. Dif measurement categories (x-values) from highest to lowest in an ordinal, ratio and interval scale (nominal scale categories can be in any order) Next to it, is the frequency (number of times it occurred in the data) By adding up the frequencies, you are able to find out the # of participants. Sum of x = adding all the x the amount of times their frequencies say. Sum of x^2 = adding all the x the amount of times their frequencies say & squaring it.
