Question

find the midrange for the following group of data items. 87, 88, 89, 93, 92, 88 the midrange is (type an integer or a decimal)

Explanation:

Step1: Find the maximum and minimum values

The data set is \(87, 88, 89, 93, 92, 88\).
The minimum value \(min = 87\).
The maximum value \(max=93\).

Step2: Calculate the midrange

The formula for midrange is \(Midrange=\frac{min + max}{2}\).
Substitute \(min = 87\) and \(max = 93\) into the formula:
\(Midrange=\frac{87 + 93}{2}=\frac{180}{2}=90\).

Answer:

\(90\)
