how to make a box plot

Answer 1

How to make a Box-and-whisker plot:

1. organize your data points from least to greatest.
2. find the median (middle number), as this will also be our second quartile (we have four in total.)
3. find the first and third quartiles by finding the median of both the lower and upper halves made from the numbers left over from your previous median.
4. draw a plot line and mark your quartiles with vertical lines and box them in.
5. mark your outliers, the smallest and largest numbers with dots and connect them to your box
