Question

Philoid · Accepted Answer

The given observations are in ascending order. Adding a row corresponding to cumulative frequencies to the given data, we get,

Now, N=29 which is odd.

Since, 15^th observation lie in the cumulative frequency 21, for which the corresponding observation is 30.

Now, absolute values of the deviations from the median,

We have, and
