Question

find the midrange for the data items in the given frequency distribution.

score, x	90	91	92	93	94	95	96	97
frequency, f	1	1	2	5	5	6	6	2

the midrange is (type an integer or a decimal.)

Explanation:

Step1: Identify the minimum and maximum values

The minimum value of the score $x$ is 90 and the maximum value is 97.

Step2: Calculate the mid - range

The formula for the mid - range is $\frac{\text{Minimum value}+\text{Maximum value}}{2}$. So, $\frac{90 + 97}{2}=\frac{187}{2}=93.5$.

Answer:

93.5
