In order to understand the differences between the mean, median, and mode, letâs start by defining the terms. 1  The mean is the arithmetic average of a set of given numbers. 2  The median is the middle score in a set of given numbers. 3  The mode is the most frequently occurring score in a set of given numbers.
Variability can also be defined in terms of how close the scores in the distribution are to the middle of the distribution. Using the mean as the measure of the middle of the distribution, the variance is defined as the average squared difference of the scores from the mean. The data from Quiz 1 are shown in Table 1. The mean score is 7.0. Therefore, the column Deviation from Mean contains the score minus 7.
