For example: for a given set of two numbers such as 3 and 1, the geometric mean is equal to √ (3×1) = √3 = 1.732. In other words, the geometric mean is defined as the nth root of the product of n numbers.

Mean = Sum of data values/Total number of data values. = (40 + 50 + 55 + 78 + 58)/5. = 281/5. = 56.2. Therefore, the mean for the given data is 56.2. 2.
