For an ungrouped data comprising ‘n’ observations, how is median calculated if ‘n’ is even. |
|
Answer» Total number of observations are n, where n is an even number. Then the median is calculated by the average of \(\frac{n}{2}^{th} and (\frac{n}{2}+1)^{th}\) observations. Hence, median = \(\frac{\frac{n}{2}^{th} observation + (\frac{n}{2}+1)^{th} observation}{2}\) |
