Mill Media Size Calculation

Mean Median Mode Range Calculator

In statistics the mode is the value in a data set that has the highest number of recurrences It is possible for a data set to be multimodal meaning that it has more than one mode For example 2 10 21 23 23 38 38 Both 23 and 38 appear twice each making them both a mode for the data set above Similarly to mean and median the mode is used
