This central tendency statistics math video tutorial explains how to calculate the mean, median, mode, and range given a data set of odd numbers and even numbers. The average / arithmetic mean is the sum of all numbers divided by the number of terms in a sequence. The median is simply the middle number. In an even data set, the median is the midpoint or average of the two middle numbers. The mode is number with the highest frequency or the number that appears most often. The range is the difference between the highest number and the lowest number. This video contains plenty of examples and practice problems.
