The median (MD) is the score at the exact center of the ungrouped frequency distribution. It is the 50th percentile. To obtain the MD, sort the values from lowest to highest. If the number of values is an uneven number, exactly 50% of the values are above the MD and 50% are below it. If the number of values is an even number, the MD is the average of the two middle values. The median for this set is 7.5, since the data set contains an even number of values, and the two numbers in the middle are 7 and 8. Their average is 7.5.
