<\/p>\nArithmetic mean is the central value of the distribution in the sense that positive and negative deviations from the arithmetic mean balance each other. It is a quantitative average.<\/p>\n
On the other hand, median is the central value of the distribution in the sense that the number of values less than the median is equal to the number of values greater than the median. So, median is a positional average.<\/p>\n
Median is the central value in a sense different from the arithmetic mean. In case of the arithmetic mean it is the \u201cnumerical magnitude\u201d of the deviations that balances. But, for the median it is the \u2018number of values greater than the median which balances against the number of values of less than the median.<\/p>\n
In general, if we have n values of x, they can be arranged in ascending order as:<\/p>\n
x1 < x2 < … < xn<\/p>\n
Suppose n is odd; then the median is the (n+1)\/2 th value.<\/p>\n
However, if n is even, we have two middle points<\/p>\n
<\/p>\n
Identify the median class which contains the middle observation (N+1)\/2 observation. This can be done by observing the first class in which the cumulation frequency is equal to or more than (N+1)\/2<\/p>\n
Here, N = \u03a3f = total number of observations.<\/p>\n
Calculate Median as follows:<\/p>\n
