Question

What is the mode of this data set? {8, 11, 20, 10, 2, 17, 15, 5, 16, 15, 25, 6}

Answer 1

Mode is the number that appears most in a set of numbers. Every number appears once besides 15 which appears twice so 15 would be the mode.

Answer 2

Given:

$8, 11, 20, 10, 2, 17, 15, 5, 16, 15, 25, 6$

Numerical Order:

$2,5, 6, 8, 10, 11, 15, 15, 16, 17, 20, 25$

Median:

$11,12,13,14,15$

Process Of Elimination

$\left[\begin{array}{ccc}13\end{array}\right]$

Mode:

$2,5, 6, 8, 10, 11, 15, 15, 16, 17, 20, 25$

Process Of Elimination

$15,15$

$\left[\begin{array}{ccc}15\end{array}\right]$

Range:

$2,5, 6, 8, 10, 11, 15, 15, 16, 17, 20, 25$

$\left[\begin{array}{ccc}25-2\end{array}\right]$

$\left[\begin{array}{ccc}23\end{array}\right]$
