66, 66, None, 27
Explanation:
The Mean is the arithmetic average
(68.4 + 65.7 + 63.9 + 79.5 + 52.5)/5 = 66
The Median is the value equidistant (numerically) from the range extremes.
79.5 – 52.5 = 27 27/2 = 13.5 ; 13.5 + 52.5 = 66
NOTE: In this set of data it is the same value as the Mean, but that is not usually the case.
The mode is the most common value(s) in a set. There is none in this set (no duplicates).
The range is the numerical value of the difference between the lowest and highest values. 79.5 – 52.5 = 27
