Suppose data collected on rain fall in(mm) of 390 metrological stations were tabulated in frequency distribution and the following result were obtained.
frequency: 6, 25, 48, 72, 116, 60, 38,22,3
CM1=110; CM2=120, where ;CMi is class marks of ith class and assume the size of the class interval(w) are equal.
Determine:-
a. Class interval size, class boundaries and class marks(class mid point) of each class.
b. Compute the mean, median and the modal rain fall of the distribution.
