Question

What is the median value of the data set shown on the line plot? Enter your answer in the box. A line plot with twenty-two data values. Labels are at zero, three, six, nine, and twelve. Tick marks are every one unit. Values appear as x marks above the line. Plot data values are one x mark above one, one x mark above two, two x marks above three, two x marks above four, three x marks above five, four x marks above six, three x marks above seven, three x marks above eight, two x marks above nine, and one x mark above eleven.

Answer 1

The median is 6.

This median is easy to find-- you place all your numbers in numerical order and choose the number(s) in the middle-- for this question the median is 6.

I believe your line plot looks like this [Screenshot was taken on K12]:

Answer 2

The median is the value that can be found in the middle of any data set. After plotting the values on the line plot (shown in the attached image), we can write out our data (shown under neath the line plot).

Then, we start by crossing off one value on each side of the data to work our way towards the middle. Once we come to the middle, we see that there are two values in the middle: 6 and 6.

To find the median when we have two values in the middle, we must add them, then divide by two.

6 + 6 = 12

12 ÷ 2 = 6

So, the median for this data set is 6.
