Question

what is the range of this set of test scores? {76, 82, 54, 100, 100, 82, 100, 93, 100, 93}

Explanation:

Step1: Find the maximum value

In the set \(\{76, 82, 54, 100, 100, 82, 100, 93, 100, 93\}\), the maximum value \(M = 100\).

Step2: Find the minimum value

In the set \(\{76, 82, 54, 100, 100, 82, 100, 93, 100, 93\}\), the minimum value \(m=54\).

Step3: Calculate the range

The formula for the range \(R\) of a data - set is \(R = M - m\). Substitute \(M = 100\) and \(m = 54\) into the formula: \(R=100 - 54\).

Answer:

\(46\)
