How can we find the median? |
|
Answer» Median can be found by a method which has a formula... median= l+(n/2-F÷f)h. l is the lower limit of the median class (when class intervals are given) n= summasion of all frquencies F=cumulative frequency of the class preceeding the median class f=frequency of median class and h= class width. Median is a measure of central tendency which gives the value of the middle most observation in the data. For finding the median you firstly have to arrange the data in the ascending order and in a frequency distribution table. Then apply the formula: if n is odd then median will be(n+1)/2 th observation. If n is even then median will be average of n/2 and (n/2+1). And the median fpr the grouped data can be find out by : median= l+(n/2-cf/f)×h. Here l =lower limit, n=number of observations, cf= cumulative frequency of class preceding the median class, f= frequency, h = class size. |
