Document Summary
Mean = numerical average; found by adding up all of the values + dividing by the total number of values. Median = middle value after the numbers have been put in order; value that has half of ordered list of numbers at or above it + half of ordered list at or below it. Mode = if one or more values occur more than once, most common one -> mode. Odd # of values -> one in middle is median. Even # of values -> take average of two middle values. Can occur anywhere in data set -> does not generally represent center. Generally categorized into four kinds of information. Mean and median as measures of center. Outliers = if one or more values are far removed from the rest of the data set. Outlier is legitimate data value + represents natural variation in responses. Mistake made when recording measurement or question was misunderstood.
