📚 Topic Summary
The median is the middle value in a dataset when the data is ordered from least to greatest. It's a measure of central tendency that describes the "center" of the data. To find the median, you first need to sort your data. If there's an odd number of values, the median is simply the middle number. If there's an even number of values, the median is the average of the two middle numbers.
For example, given the dataset: 3, 1, 7, 2, 5. First, we sort it: 1, 2, 3, 5, 7. The median is 3 because it's in the middle.
