Write the formula of median for ungroped data ?
Answers
Answer:
This formula is used to find the median in a group data which is located in the median class. Median, m = L + [ (N/2 – F) / f ]C L means lower boundary of the median class N means sum of frequencies F means cumulative frequency before the median class.

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. Here, it is possible to give a solid derivation, and to clearly state the assumptions on which it is based.
