Question

find median, mode, mean of the following distribution 10-20 20-30 30-40 40-50 50-60
​

Answer 1

Answer:

Modal class = 30 – 40, lower limit (l) of modal class = 30, class size (h) = 10, frequency (f1) of the modal class = 45, frequency (f0) of class preceding the modal class = 35, frequency (f2) of class succeeding the modal class = 25 Now, let us substitute these values in the formula: = 30 + 3.33 = 33.33 Hence, the mode is 33.33.Read more on Sarthaks.com - https://www.sarthaks.com/1150593/find-the-mode-of-the-following-distribution-marks-10-20-20-30-30-40-40-50-50-60
