Question

find mode of 1, 1, 1, 2, 2, 2, 3, 3, 3, 4, 4, 4​

Answer 1

the numbers are already arranged in ascending order so,we don't have to arrange them in ascending order

the mode is the number which appears the most times

Therefore, the mode are 1,2,3and 4 because all of these appears three times

Answer 2

Answer:

Mode = 3 Median – 2 Mean ........(i)

now Mean = (1+1+1+2+2+2+3+3+3+4+4+4)/12 = 30/12 = 5/2 = 2.5

Median = (2+3)/2 = 2.5

from (i)

Mode = 3×2.5 – 2×2.5 = 2.5 Ans.
