Question

(ii) 68.4, 65.7, 68.9, 79.5, 52.5 find median​

Answer 1

Step-by-step 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
