How to Calculate the Midrange

The midrange is a measure of central tendency that represents the average of the minimum and maximum values in a dataset. It's simple to calculate but can be sensitive to extreme values.

Midrange Formula

The formula for calculating the midrange is:

\[ \text{Midrange} = \frac{\text{Minimum value} + \text{Maximum value}}{2} \]

Where:

• Minimum value is the smallest number in the dataset
• Maximum value is the largest number in the dataset

Calculation Steps

1. Identify the minimum value in the dataset.
2. Identify the maximum value in the dataset.
3. Add the minimum and maximum values.
4. Divide the sum by 2.

Example

Let's calculate the midrange for the dataset: 4, 7, 9, 3, 2, 7

1. Minimum value: 2
2. Maximum value: 9
3. Apply the formula:

   \[ \text{Midrange} = \frac{2 + 9}{2} = \frac{11}{2} = 5.5 \]

Visual Representation

This diagram illustrates the midrange for the example dataset. The red dashed line represents the midrange value (5.5), which is the average of the minimum (2) and maximum (9) values.
