Median formula for cumulative frequency
WebFor even number of observations, Median = [ (n/2)th term + ( (n/2) + 1)th term]/2 For grouped data: Median = l + [ ( (n/2) - c)/f] × h where, l = Lower limit of the median class c = Cumulative frequency h = Class size n = Number of observations Median class = Class where n/2 lies Let us use the same example given above to find the median now. WebIf you have n numbers in a group, the median is the (n + 1)/2 th value. For example, there are 7 numbers in the example above, so replace n by 7 and the median is the (7 + 1)/2 th value = 4th value. The 4th value is 6. When …
