Measures of Center: Mean, Median, and Mode Measures of center generally tell us about the middle, or center, of a distribution. They are the mean, the median, and the mode. Each plays a useful role in Statistics. The Mean The mean, or arithmetic average, is calculated by adding all the data values and dividing by the number of values.
The term measures of central tendency refers to finding the mean, median and mode. Mean: Average. The sum of a set of data divided by the number of data. (Do not round your answer unless directed to do so.) Median: The middle value, or the mean of the middle two values, when the data is arranged in numerical order.Think of a median being in the middle of a highway.he set on the right shows what would happen if one of the scores was WAY out of range in regard to the other scores. Such a term is called an outlier. With the outlier, the mean changed. With the outlier, the median did NOT change.
