Median Calculator – Formula, Free Online Tools, Mobile Apps & FAQs for South Africans
What Is a Median?
A median is a statistical measure that represents the middle value in a set of numbers. It is useful in South Africa for determining central tendencies in data and finding the midpoint in distributions.
How to Calculate Median Manually
The formula to calculate the median depends on whether the number of values in the dataset is odd or even. For an odd number of values, simply find the middle number. For an even number of values, calculate the average of the two middle numbers.
For example, let’s consider the following dataset in South Africa: 10, 15, 20, 25, 30. Since there are 5 values (odd), the median would be the middle value, which is 20.
