# Median The median is the center of your data set. A way of thinking about how to calculate it is lay all your numbers out in a line in order of least to greatest. Then remove one from each side until you're left with 1 or 2 numbers. The numbers you are left with will tell you the median value: | First Num | Second Num | | ------- | -------- | | 5 | 7 | with 2 numbers we take the [[Mean]] of those 2 numbers or: $\frac{(5 + 7)}{2}=6$ $\frac{12}{2}=6$ If you are left with only 1 number after equally removing values from both sides then *that* number is your median or central point of your data. | First Num | Second Num | Third Num| | ------- | -------- |-------- | | 5 | 7 | 9| In this case you remove `5` and then remove `9` and you are left with `7` this is the median of that small sample. # Code ```r # Documentation median(x) ``` --- References: - [[Mode]] - [[Mean]]
