Question

ch 2 in january of 2006, a family moved to a tropical climate. for the year that followed, they recorded the number of rainy days that occurred each month. the data contained: 14, 14, 10, 12, 11, 13, 11, 11, 14, 10, 13, 8. what is the median? 12 11.5 11 13

Explanation:

Step1: Sort the data

8, 10, 10, 11, 11, 11, 12, 13, 13, 14, 14, 14

Step2: Determine the position

There are $n = 12$ data - points. Since $n$ is even, the median is the average of the $\frac{n}{2}$-th and $(\frac{n}{2}+ 1)$-th ordered data - points. $\frac{n}{2}=\frac{12}{2}=6$ and $\frac{n}{2}+1 = 7$.

Step3: Calculate the median

The 6 - th value is 11 and the 7 - th value is 12. The median is $\frac{11 + 12}{2}=11.5$.

Answer:

11.5
