Question

find the midrange for the following group of data items. 84, 85, 86, 90, 89, 85 the midrange is (type an integer or a decimal.)

Explanation:

Step1: Find the maximum and minimum values

The given data items are \(84, 85, 86, 90, 89, 85\).
The minimum value \(min = 84\).
The maximum value \(max=90\).

Step2: Calculate the mid - range

The formula for the mid - range is \(Mid - range=\frac{min + max}{2}\).
Substitute \(min = 84\) and \(max = 90\) into the formula: \(Mid - range=\frac{84 + 90}{2}=\frac{174}{2}\).

Answer:

\(87\)
