Data Analysis and Probability Find the mean, median, mode, and range of a set of data. –Mean: sum of a set of numbers divided by the number of pieces of data in the set (also referred to as the average) –Median: The middle value in a set of data when the data are listed in order from smallest to largest. In an even number of data, the median is the mean of the two middle values. –Mode: The value or values that occur most often in a set of data. –Range: The difference of the maximum and minimum of a set of data.
