Question

Find the mean, median and mode of the following distribution:
8,10, 7, 6,10,11, 6,13,10

Answer 1

Arranging the number of in ascending order 6, 6, 7, 8, 10, 10, 11, 13.
Mean `bar"X" = (sumx)/"n" = (81)/(9) = 9`.
Median = `[("n" + 1)/2]^"th" "term"`
= `((9 + 1)/2)^"th"`
= 5^th term
Median = 10.
Mode = 10 is repeating 3 times which is highest frequences.
So mode is 10.
