Question

the following list contains the number of movies that a group of 8 students saw in theaters in the past 12 months. 12, 18, 8, 4, 18, 17, 14, 14. find the median number of movies that the students saw. send data to calculator

Explanation:

Step1: Arrange data in ascending order

$4,8,12,14,14,17,18,18$

Step2: Determine the middle - value position

Since there are $n = 8$ data points (an even number of data points), the median is the average of the $\frac{n}{2}$th and $(\frac{n}{2}+ 1)$th ordered data values. $\frac{n}{2}=\frac{8}{2}=4$ and $\frac{n}{2}+1 = 5$.

Step3: Calculate the median

Median=$\frac{14 + 14}{2}=14$

Answer:

$14$
