The median formula is {(n + 1) ÷ 2}th, where “n” is the number of items in the set and “th” just means the (n)th number. To find the median, first order the numbers from smallest to largest. ... For example, the middle for this set of numbers is 5, because 5 is right in the middle: 1, 2, 3, 5, 6, 7, 9.

Answer:
median tells you where the middle of a data set is. It’s used for many real-life situations, like Bankruptcy law, where you can only claim bankruptcy if you are below the median income in your state.

The median formula is {(n + 1) ÷ 2}th, where “n” is the number of items in the set and “th” just means the (n)th number.
To find the median, first order the numbers from smallest to largest. Then find the middle number. For example, the middle for this set of numbers is 5, because 5 is right in the middle:
1, 2, 3, 5, 6, 7, 9.
You get the same result with the formula. There are 7 numbers in the set, so n = 7:
{(7 + 1) ÷ 2}th
= {(8) ÷ 2}th
= {4}th
The 4th number in 1, 2, 3, 5, 6, 7, 9 is 5.
A caution with using the median formula: The steps differ slightly depending on whether you have an even or odd amount of numbers in your data set.
