Answer» Correct Answer - D `{:(x,f,"Cumulative frequency"),(12,4," "14),(15,7," "11),(18,2," "13),(21,3," "16),(24,4," "20):}` N=20 The value of x corresponding to `(N)/(2)`th value class in the cumlative frequency is the median. Here `(N)/(2) = 10` and the corresponding x value is median, i.e., 15. |
