What is the range of the following set of sata.? 23,45,18,65,88,14,56,21,57.?

The range of a set of data is the difference between the largest and smallest values in the set.

In this case, the largest value is 88 and the smallest value is 14.

Therefore, the range of the set of data {23,45,18,65,88,14,56,21,57} is 88 - 14 = 74.

Range = Highest value - Lowest value
= 88 - 14
= 74
