Stem and leaf plot.
Work Step by Step
First of all, you must sort the numbers. 10, 15, 15, 18, 22, 25, 28, 35, 36. Create a key for your Stem and leaf plot, which in this case, I will use $2|2 = 22$ Create a stem and leaf plot and on the left side, put $1$ $2$ $3$ This represents the tens place. On the right side, put the ones place of each number on the side of the appropriate tens place.
