(See Exercise 5 from "Problems on Distribution and Density Functions"). In a thunderstorm in a national park there are 127 lightning strikes. WebCalculation of median of raw data: (i) If the number of observations ‘ n ’ is odd, then the median will be the value of observation. (ii) If n is even, then we have two middle terms i.e. (n/2) th observation and (n/2 + 1) th observation. Median of the given data will be mean of these two middle observations.
