Give the median of the following six scores:
83, 87, 99, 90, 82, 84
Give the median of the following six scores:
83, 87, 99, 90, 82, 84

To find the median of a group of scores, first, arrange the scores from least to greatest:
There are an even number of scores, so the median is the mean of the two scores that fall in the middle, which are noted in red above. Add the scores and divide by two:
