Calculating Mean, Median, and Mode (Individual Data) Individual data – represents individual values in a set. Mean – is the average value of the values in a set. It is calculated by dividing the sum of the individual values in a set by the number of values in that set. Median – better represents a measure of central than the mean in a set of data that are skewed one direction or another. To calculate the median value of individual...
