Question

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

Answer 1

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]`

Answer 2

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.
