We discussed the mean of group data formulas;

Median formula for group data. See the cumulative frequency ( ‹c) just greater than ½ n and. Median is the value which occupies the middle position when all the observations are arranged in an ascending or descending order. N is the total number of values ;.

This statistics video tutorial explains how to calculate the mean of grouped data. Select a blank cell and type this =median(b2: The median is (n/2) th value = 30 th value.

Find (n/2) th term (iii). We first arrange the given data values of the observations in ascending order. For example, suppose we have the following grouped data:

The median of the data is. Now you need to find the middle. What is the formula for median of grouped data?

And this handy formula does the calculation: Finding median for grouped data. Find the cumulative frequencies ( ‹c) step 2:

Find ½ n where n =∑ ni=1 fi. Median of a data is, the value that has equal number of smaller and larger data values in the given data. Number of pens carried by 10 students.
