What is the median of the data set

median = 4

Step-by-step explanation:

First the solve this problem, we have to know how to solve for the median.

The median is the MIDDLE of the data set when written in order from least to greatest.

Now that we know, let's list the data set from least to greatest (in order) and the to the number that is in the middle:

This data set has 15 points: 2, 2, 2, 3, 4, 4, 4, 4, 6, 6, 7, 7, 7, 8, 9.

Now that we have all of the data laid out in order, let's look for the number that is in the middle.

To calculate what's in the middle of 15, do (15-1)/2 which is 7, and then add one. So your 8th term would be your median and your 8th term is 4 so therefore your median is 4.

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier
