Our free midrange calculator provides an easy way to compute the midrange of a dataset. It quickly identifies the maximum and minimum values and allows you to calculate other basic statistics such as median, mode, range, standard deviation, variance, sum, and count.

What is Midrange in Math?

The midrange is the arithmetic mean of the smallest and largest values in a dataset, representing a simple measure of central tendency.

Formula:

M = (X_max + X_min) / 2

M = midrange
X_max = maximum value
X_min = minimum value

Example:

Find the midrange of the dataset {6, 6, 12, 15, 7}.

Solution:

Minimum value = 6

Maximum value = 15

Midrange = (6 + 15) / 2 = 10.5

Other Basic Statistics

Median

The median is the middle value of an ordered dataset. For even-numbered datasets, it is the average of the two middle numbers.

Example: Dataset {3, 13, 2, 34, 11, 26, 47}

Sorted: {2, 3, 11, 13, 26, 34, 47} → Median = 13

Mode

The mode is the value that appears most frequently in a dataset.

Example: Dataset {4, 2, 4, 3, 2, 2} → Mode = 2

Range

The range measures the spread of a dataset and is calculated as the difference between the maximum and minimum values.

Formula: Range = Maximum value − Minimum value

Example: Dataset {53, 50, 60, 51, 48, 93, 80, 92, 71, 90} → Range = 93 − 48 = 45

Standard Deviation

The standard deviation (σ) quantifies the average deviation of data points from the mean.

Formula:

$$ \sigma = \sqrt{\frac{1}{N} \sum_{i=1}^{N} (x_i - \mu)^2} $$

σ = standard deviation
x_i = each data value
μ = mean
N = number of values

Variance

Variance measures the spread of data points around the mean and is the square of the standard deviation.

Formula:

$$ \sigma^2 = \frac{\sum (x_i - \mu)^2}{N} $$

FAQs

Are mode and modal the same?

Yes, both refer to the most frequently occurring number in a dataset.

What is the difference between mean and median?

The mean (average) is the sum of values divided by the count, while the median is the middle value when the data is sorted.

What does low or high variance indicate?

Low variance means data points are close to the mean; high variance means they are spread out.

Conclusion

The midrange is a simple statistical tool for understanding the center of a dataset. Using a midrange calculator saves time and helps compute related statistics efficiently.
