Detailed explanation-1: -The difference between the maximum and the minimum value of the observations in a data-set is called range.
Detailed explanation-2: -The largest value in a data set is often called the maximum (or max for short), and the smallest value is called the minimum (or min). The difference between the maximum and minimum value is sometimes called the range and is calculated by subtracting the smallest value from the largest value.
Detailed explanation-3: -All we need to do is find the difference between the largest data value in our set and the smallest data value. Stated succinctly we have the following formula: Range = Maximum Value–Minimum Value. For example, the data set 4, 6, 10, 15, 18 has a maximum of 18, a minimum of 4 and a range of 18-4 = 14.
Detailed explanation-4: -The difference between the maximum and minimum observations in the data is called range. So, the correct answer is “Option B”.
