Question

find the midrange for the following group of data items. 33, 30, 29, 28, 34, 31, 27, 29 the midrange is (type an integer or a decimal.)

Explanation:

Step1: Find the maximum and minimum values

Given data items: \(33, 30, 29, 28, 34, 31, 27, 29\)
The maximum value \(M = 34\)
The minimum value \(m=27\)

Step2: Calculate the mid - range

The formula for mid - range is \(Mid - range=\frac{M + m}{2}\)
Substitute \(M = 34\) and \(m = 27\) into the formula:
\(Mid - range=\frac{34+27}{2}=\frac{61}{2}=30.5\)

Answer:

\(30.5\)
