Study Notes
Finding the Median
- To find the median of a dataset, sort the data points in ascending order.
- If the number of data points is odd, the median is the middle data point. This is the (n + 1) / 2 data point.
- If the number of data points is even, the median is the average of the two middle data points. These are the n/2 and (n/2 + 1) data points.
