(An archive question of the week) Last time we looked at a formula for approximating the mode of grouped data, which works well for normal distributions, though I have never seen an actual proof, or a statement of conditions under which it is appropriate. We have also received questions about a much more well-known, and well-founded, formula to estimate the median.

Refer the below median formula for grouped data to calculate the middle value for the given data. To calculate this, divide the total number of values by 2 for even data set and for odd data series, add one with the total number of values and then divide it by 2. Sort the data in ascending order before calculating the mean of a set.
