How does a median filter work

WebTo calculate a conditional median based on one or more criteria you can use an array formula that uses the MEDIAN and IF functions together. In the example shown, the formula in F5 is: =MEDIAN(IF(group=E5,data)) where "group" is the named range B5:B14, and "data" is the named range C5:C14. Note: this is an array formula and must be entered with control … WebOct 2, 2024 · The median is the value that’s exactly in the middle of a dataset when it is ordered. It’s a measure of central tendency that separates the lowest 50% from the highest 50% of values. The steps for finding the median differ depending on whether you have an odd or an even number of data points.
