-# Median
-
-The median is the value separating the higher half from the lower half of a data sample
-(a population or a probability distribution). For a data set, it may be thought of as the
-"middle" value.
-
-`median` is not an accurate average. However, it eliminates all spikes, by sorting
-all the values in a period, and selecting the value in the middle of the sorted array.
-
-Netdata also supports `trimmed-median`, which trims a percentage of the smaller and bigger values prior to finding the
-median. The following `trimmed-median` functions are defined:
-
-- `trimmed-median1`
-- `trimmed-median2`
-- `trimmed-median3`
-- `trimmed-median5`
-- `trimmed-median10`
-- `trimmed-median15`
-- `trimmed-median20`
-- `trimmed-median25`
-
-The function `trimmed-median` is an alias for `trimmed-median5`.
-
-## how to use
-
-Use it in alerts like this:
-
-```
- alarm: my_alert
-    on: my_chart
-lookup: median -1m unaligned of my_dimension
-  warn: $this > 1000
-```
-
-`median` does not change the units. For example, if the chart units is `requests/sec`, the result
-will be again expressed in the same units. 
-
-It can also be used in APIs and badges as `&group=median` in the URL. Additionally, a percentage may be given with
-`&group_options=` to trim all small and big values before finding the median.
-
-## Examples

-Examining last 1 minute `successful` web server responses:
