Question

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

score, x	17	18	19	20	21	22	23	24
frequency, f	2	5	1	3	5	5	3	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 $17$ and the maximum value is $24$.

Step2: Calculate the mid - range

The formula for the mid - range is $\text{Mid - range}=\frac{\text{Minimum}+\text{Maximum}}{2}$. So, $\text{Mid - range}=\frac{17 + 24}{2}=\frac{41}{2}=20.5$.

Answer:

$20.5$
