Calculate the mode of each of the following using the empirical formula:
17, 10, 12, 11, 10, 15, 14, 11, 12, 13

Answer :

By arranging the given data in ascending order we will get,


10, 10, 11, 11, 12, 12, 13, 14, 15, 17



We have;


N = 10 (even number)


Median =





Now,


∑fx = 125 and ∑f = N = 10


Mean =


Hence,


Mode = 3(median) – 2 (mean)


= 3×12 - 2×12.5


= 36 – 25


= 11
