the data set represents the total number of tickets each person purchased for a play. 0,0,1,1,1,2,2,2,4,4…

Explanation:

Step1: Arrange data in ascending order

The data 0, 0, 1, 1, 1, 2, 2, 2, 4, 4 is already in ascending - order.

Step2: Determine the number of data points

There are $n = 10$ data points.

Step3: Use the median formula for even - numbered data sets

For an even - numbered data set, the median is the average of the $\frac{n}{2}$th and $(\frac{n}{2}+1)$th ordered data values. Here, $\frac{n}{2}=\frac{10}{2}=5$ and $\frac{n}{2}+1 = 6$. The 5th value is 1 and the 6th value is 2. Median=$\frac{1 + 2}{2}=\frac{3}{2}=1.5$

Answer:

1.5
