Answer

Explanation:

Step1: Count the number of data - points

There are 7 data - points (dots) on the dot - plot.

Step2: Arrange the data in ascending order

The data values are 1, 1.5, 2, 2.5, 2.5, 3, 4.

Step3: Find the median

For a set of (n = 7) (odd number of) data - points, the median is the (\left(\frac{n + 1}{2}\right))-th value. (\frac{7+1}{2}=4)-th value. The 4 - th value in the ordered list is 2.5.

Answer:

2.5
