midrange for the following group of data items: \( 50,72,12,67,8,30 \)

To find the midrange, you first determine the maximum and minimum values in your dataset. In this case, the maximum is 72, and the minimum is 8. The midrange is then calculated by averaging these two numbers: \[ \text{Midrange} = \frac{\text{Max} + \text{Min}}{2} = \frac{72 + 8}{2} = \frac{80}{2} = 40. \] So, the midrange for the data set \( 50, 72, 12, 67, 8, 30 \) is 40. Just a tip: The midrange can be sensitive to outliers! If you had a very high or very low number compared to the rest, it could skew your midrange.
