4.3 Numerical Smoothing using the Moving Median Method

Note: if you can’t remember the basics of numerical smoothing, revise notes for 4.2 Numerical Smoothing using the Moving Mean Method.

Moving Median Smoothing

  • The moving median smoothing method involves taking the median of each group.
  • This method is particularly effective when the exact values of data points are unknown (e.g. if the data is shown in a time series plot without the raw dataset).
