Question

For which set of number do the mean, median and mode all have the same value?

A. 2, 2, 2, 2, 4

B. 1, 3, 3, 3, 5

C. 1, 1, 2, 5, 6

D. 1, 1, 1, 2, 5

Answer 1

Correct answer is B.

1, 3, 3, 3, 5

Mean \(=\frac{(1+3+3+3+5)}{5}\)

\(=\frac{15}{5}\)

= 3

Median = 3^rd term

= 3

Mode = 3 (The highest occurring number)
