The median in this example would be 28 and the mean is 37.2. There is no mode for the example above because there are no numbers repeating themselves.

As central tendency refers to the middle of the distribution, variability is about the spread of the distribution. Variability is important because of the range of difference between the low score and the high score. The range, standard deviation, and the variance are all important parts of the variability. In the case of BMIS, if the scores are greatly different, then there will be a much larger spread within the distribution. The less difference in the scores means less variability.
