I have two box plots that I'd like to add together to form one box plot representing both plots in one. Here's an example of two box plots:
At a school 200 boys and 200 girls participated in a test. The maximum score were 80 points. I've included an example image of what the box plots could look like.
How would I do to add these two box plots together to form one box plot with a total of 400 students and their test results?
Thank you for your help! If you need me to explain what I'm looking for any further, please don't hesitate to ask. Thank you!
