What do you mean by Median?

It is a type of measure of central tendencies, used to measure and analyse the given observations. When grouped observations are given, we measure the median as follows: 1. Arrange the data in either ascending or descending order. Count the number of observations. If number of observations are even, take the average of middle most observations. If the number of observations are odd, take the middle most observation as the median. For grouped data: 1. Write the cumulative frequencies. 2. Find sum of all frequencies and take half of the sum. 3. Take the cumulative frequency that is just greater than half of sum of the frequencies. The class that has the required feature (just above the half of the sum of frequencies) will become the modal class. Take the values from the table and substitute in the formula to get the median. Median = L+({N/2-F}/f)*h. read less
