The average is defined as the mean value that is equal to the ratio of the sum of the variety of a given set of values to the entire number of values present within the set. The mode is the number in a set of numbers that appears the most often. The mean of a set of numbers is the sum of all the numbers divided by the number of values in the set. The mean is also called the average.
The mean (average) of a data set is found by including all numbers in the information set after which dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest. The mode is the variety that occurs most often in a data set.
