Document Summary

Chapter 3- statistics for exploring and comparing data. Definitions: mean= the measure of the center of a set of data. = found by adding the data values and dividing the total by the number of data values. =also know as the average: median= measure of the middle value. = found when the original data values are arranged in increasing order: mode= greatest occurring number, midrange= the measure of center that is the value midway between the maximum and minimum values in the original data set. = found by converting a value to a standardized scale: percentile= measure of location. Finding the mean: considered the most important of all numerical measurements (sum of all data values) / (number of data values) ( x) / (n) or. Finding the mode: data sets can have, one mode, multiple modes, no modes at all.
