how to calculate the mean median and mode of grouped data. For the grouped frequency distribution of a discrete variable or a continuous variable the calculation of the median involves identifying the median class ie. 2Mean Mode 3Median2Mean Mode 3Median For instance if we are asked to calculate the mean median and mode of a continuous grouped data then we can calculate mean and median using the formulae as discussed in the previous sections and then find mode using the empirical relation.

Next line contains Frequency values with sepearated. To find the MEAN or Mathematically Estimated Average Number involves adding two extra columns to our original Frequency Table. In statistics the most common measures of central tendency are the mean median and mode.
Draw two cross lines as shown in the diagram.
Hence the mode is 23. Hence the mode is 23. Drop a perpendicular from the intersection of the two lines. While the mean and median require some calculations a mode value can be found simply by counting the number of times each value occurs.
