If there are two middle values, then the median is the mean of the two numbers. ex: given the values: 1, 2, 4, 5, 9, 9, 9. we have seven values, so the median is 5 because 5 is in the middle (it has three values above and below it) the mean is then 5.6 and the mode is 9 Choosing the "best" measure of center. There are other types of means. The median often better expresses the common-run, since it is not, as is the mean, affected by an excessively high or low figure. To find the average, you would first add all four scores together, then divide the sum by four. If there are an even number of values in the data set, the median is the arithmetic mean of the two middle numbers.

If there are an even number of values in the data set, the median is the arithmetic mean of the two middle numbers. Mean (or average) and median are statistical terms that have a somewhat similar role in terms of understanding the central tendency of a set of statistical scores. For example, let's say you have the following list of numbers: In this case, the mode is 15 because it is the integer that appears most often. Several kinds of mean exist, and the method of calculating a mean depends upon the relationship known or assumed to govern the other members. The mode is one of the most common ways to describe a set of data. Introduction to Mean Median Mode. The result is the median number.
