Count the number of terms

Count the total number of observations in the set {10, 13, 14, 17, 18}.

$n = 5$

Check if ordered

The data set is already arranged in ascending order: 10, 13, 14, 17, 18.

$10 < 13 < 14 < 17 < 18$

Apply Median formula

Since $n$ is odd, use the formula $\text{Median} = (\frac{n+1}{2})^{\text{th}}$ position.

$\frac{5+1}{2} = 3^{\text{rd}} \text{ term}$

Identify the value

The 3rd term in the sorted sequence 10, 13, 14, 17, 18 is 14.

$\text{Median} = 14$
