There are two main possibilities to calculate the median value for a series:
1. Statistics analysis
Add “Median” as a calculation. You can also set the data range over which you want to calculate the median.
2. Formulas
Median(series)
Returns the median value of a series.
Median(series, window)
Returns the median value of a series, on a rolling basis.
NOTE: if you want to calculate the median across several time series, you should use the Cross Section analysis.
