Define median. What are its merits and demerits?
Answers
Answer:
The median is a simple measure of central tendency. To find the median, we arrange the observations in order from smallest to largest value. If there is an odd number of observations, the median is the middle value. If there is an even number of observations, the median is the average of the two middle values.
Demerits : 1) For computing median data needs to be arranged in ascending or descending order. 2) It is not based on all the observations of the data. 3) It can not be given further algebraic treatment. 4) It is affected by fluctuation of sampling.
