Uncovering the Surprising Connection between Box and Whisker Plots and Averages
Hi, I'm Rachel and today we're going to be going over how to determine the mean when only given a box and whisker plot. 5 is the median of those numbers and we want to find the mean. So the mean is going to be the average of those numbers. That means that we add all the numbers together and then we divide by the number of numbers. 1 plus 3 is 4 plus 5 is 9 plus 7 is 16 plus 9 is 25. We divide 5 into 25 to get 5. So 5 in this case is our mean as well as our median. Sometimes the mean can be different than the median. But in this case, we found the mean from the box and whiskers plot and it ended up being 5.
