Consider the following sample of numbers: $$9, 18, 11, 14, 15, 17, 10, 69, 11, 13$$ The median of the sample is

To find the median of the given sample, first arrange the numbers in ascending order:

The total number of observations is $n = 10$ (an even number).

For an even number of observations, the median is the average of the $\left(\frac{n}{2}\right)^{\text{th}}$ and $\left(\frac{n}{2} + 1\right)^{\text{th}}$ terms, which are the $5^{\text{th}}$ and $6^{\text{th}}$ terms:

• $5^{\text{th}}$ term $= 13$

• $6^{\text{th}}$ term $= 14$

Hence, the correct option is (A).
