how do you find the median of a box and wisker plot? the number is 87.
I don't know.
box and wisker plot??
Whatever happened to real math?
i know right. this is hard and im in the 9th grade
First of all, do you know what median means?
The median is that point in a distribution where half the scores have a higher value and half have a lower value. It is also known as the 50th percentile or the second quartile.
I searched Google under the key words "box whisker plot" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
I hope this helps a little more. Thanks for asking.

To find the median of a box and whisker plot, you will need to examine the arrangement of the data points. The median is the middle value or the average of the two middle values when the number of data points is even.
Here's how you can find the median of a box and whisker plot:
Step 1: Identify the box
- Locate the rectangular box in the plot, which represents the middle 50% of the data.
- If the data points are arranged in ascending order, the left edge of the box represents the lower quartile (25th percentile), and the right edge represents the upper quartile (75th percentile).
Step 2: Identify the median line
- Inside the box, there is a line that represents the median. It is typically drawn as a horizontal line.
Step 3: Determine the median
- If the median line (which you mentioned is 87) is exactly in the middle of the box, then it is the median value.
- If the median line is not shown or you want to double-check, you can count the number of data points on each side of the median line. If the count is the same or almost equal, then the median is 87. If there are an odd number of data points, the median is the value at the middle data point. If there are an even number of data points, the median is the average of the two middle values.
So, if the number 87 is indicated as the median line in the box and whisker plot, then 87 is the median of the data.
