1. What is Midrange?

The midrange is a measure of central tendency that represents the middle point between the minimum and maximum values in a dataset. It's calculated as the average of the highest and lowest values.

2. How to Calculate Midrange

The midrange is calculated using the simple formula:

Steps:

1. Identify the maximum value in your dataset
2. Identify the minimum value in your dataset
3. Add these two values together
4. Divide the sum by 2

3. When to Use Midrange

Appropriate uses:

• When you need a quick estimate of central tendency
• For small datasets where extremes are meaningful
• When the data is symmetrically distributed
• In quality control processes for range calculations

4. Limitations of Midrange

Be aware that:

• Midrange is highly sensitive to outliers
• It only considers two values from the entire dataset
• Not as robust as mean or median for most analyses
• Can be misleading for skewed distributions

5. Frequently Asked Questions (FAQ)

Q1: Is midrange the same as median?
A: No, median is the middle value when all values are ordered, while midrange is the average of just the highest and lowest values.

Q2: When should I not use midrange?
A: Avoid midrange when your data has extreme outliers or is heavily skewed, as it will give a distorted view of central tendency.

Q3: What's the advantage of midrange?
A: It's extremely simple to calculate and can be useful for quick estimates with small, well-behaved datasets.

Q4: How does midrange compare to mean?
A: Mean considers all data points, while midrange only considers two. Mean is generally more representative but more affected by outliers.

Q5: Can midrange be used with any data type?
A: Midrange requires numerical data where arithmetic operations (addition and division) make sense.
