Summary
This chapter covers three different measures of central tendencies, meaning where the center of a distribution is. The
three measures covered - the mean, the median, and the mode - may each define a different point as the center. The
meanis determined by dividing the sum of all values in a data set by the number of values. Three lessons cover
calculating from raw values, frequency distribution tables (grouped), and frequency distribution tables (ungrouped).
Themedianis the value of the middle term in a set of organized data (i.e. the raw values sorted into ordered list).
Themodeof a data set is the value or values that occur with the greatest frequency in the data set.
