The following scores were obtained by the students in a test: 81, 72, 90, 90, 86, 85, 92, 70, 71, 83, 89, 95, 85, 79, 62

What is the range of scores?

The given scores are:  81, 72, 90, 90, 86, 85, 92, 70, 71, 83, 89, 95, 85, 79, 62

The range for a given data set is the difference between the highest and lowest values. 

Here, highest score = 95

and lowest score = 62

∴ Range = highest score  - lowest score

$\Rightarrow$Range = 95 - 62 = 33

Therefore, the range of scores is 33.
