Enter numbers separated by commas, spaces, or lines.
Calculation Results
Calculated using statistical midrange midpoint equations: \text{Midrange} = \frac{\text{Max} + \text{Min}}{2}
Quick Summary
The Midrange Calculator evaluates the exact midpoint average ($\text{Midrange} = \frac{\text{Max} + \text{Min}}{2}$) between the extreme minimum and maximum values in a dataset.
Formula Explanation
\text{Midrange} = \frac{\text{Maximum Value} + \text{Minimum Value}}{2}
\text{Range} = \text{Maximum Value} - \text{Minimum Value}How It Works
Midrange is a quick measure of central tendency defined as the midpoint of the range. The Midrange Calculator identifies the maximum and minimum values in your dataset and computes their exact arithmetic mean.
Step-by-Step Worked Example
Practical Problem: Calculate the midrange for the dataset: 10, 25, 40, 55, 70 ($N = 5$).
- Step 1: Identify maximum value ($\text{Max}$): $\text{Max} = \mathbf{70}$.
- Step 2: Identify minimum value ($\text{Min}$): $\text{Min} = \mathbf{10}$.
- Step 3: Add maximum and minimum: $70 + 10 = \mathbf{80}$.
- Step 4: Divide sum by 2: $80 / 2 = \mathbf{40.0000\text{ Midrange}}$.
- Step 5: Interpretation: The exact midpoint between 10 and 70 is 40.
Real-World Calculation Examples
Scenario 1: Symmetrical Dataset (10 to 70)
Parameters: 10, 25, 40, 55, 70
Result: Midrange 40.00 (Matches mean and median).
Scenario 2: Daily Temperature High/Low
Parameters: Low 50°F, High 90°F
Result: Midrange 70.00°F (Average of daily high and low).
Scenario 3: 52-Week Stock Price Extremes
Parameters: Low $20, High $180
Result: Midrange $100.00 (Midpoint of 52-week range).
Scenario 4: Negative & Positive Numbers
Parameters: Min -30, Max 50
Result: Midrange 10.00 ($(-30 + 50) / 2 = 10$).

Frequently Asked Questions (FAQ)
What is midrange in statistics?
Midrange is the arithmetic average of the maximum and minimum values in a dataset ($\text{Midrange} = \frac{\text{Max} + \text{Min}}{2}$).
How does midrange differ from median?
Midrange is the midpoint between the two extreme values; median is the middle observation position of the entire sorted dataset.
Is midrange sensitive to outliers?
Yes — because midrange depends strictly on $\text{Max}$ and $\text{Min}$, a single outlier changes the midrange significantly.
When is midrange commonly used?
Midrange is frequently used in weather forecasting (average of daily high and low temperatures) and stock trading ranges.
Can midrange be negative?
Yes — if both maximum and minimum are negative, or if the negative minimum outweighs the positive maximum, the midrange will be negative.
What is midhinge?
Midhinge is the average of the first and third quartiles ($\text{Midhinge} = \frac{Q1 + Q3}{2}$).
What is mid-range estimation efficiency?
For a uniform continuous distribution, midrange is the best unbiased estimator of the distribution mean.
How do I calculate midrange for grouped data?
Average the lower limit of the lowest class and upper limit of the highest class.
What is formula for range from midrange?
$\text{Max} = \text{Midrange} + (\text{Range} / 2)$ and $\text{Min} = \text{Midrange} - (\text{Range} / 2)$.
Can midrange equal mean and median?
Yes — in perfectly symmetrical uniform or normal distributions, Mean = Median = Midrange.
