Question

find the range of this data set: 30, 25, 35, 20, 30, 28

Explanation:

Step1: Find the maximum value

The maximum value in the data set \(30, 25, 35, 20, 30, 28\) is \(35\).

Step2: Find the minimum value

The minimum value in the data set is \(20\).

Step3: Calculate the range

The formula for the range is \(Range=Max - Min\). Substitute \(Max = 35\) and \(Min = 20\) into the formula: \(Range=35 - 20\).

Answer:

\(15\)
