Question

a simple random sample of 10 people was asked how many first cousins they have. the results are listed below. 10, 19, 20, 13, 13, 2, 10, 8, 25, 10 what is the median number of first cousins for this sample? 7.5 10 11.5 13

Explanation:

Step1: Arrange data in ascending order

2, 8, 10, 10, 10, 13, 13, 19, 20, 25

Step2: Determine position for median

Since $n = 10$ (even), median position is $\frac{n}{2}=5$ and $\frac{n}{2}+1 = 6$.

Step3: Calculate median

Median=$\frac{10 + 13}{2}=11.5$

Answer:

$11.5$
