In this plot you put the tens on the left side and ones on the right. Each value on the right is a ones value. For example, if you were to have a value of 35 you would put 3 on the left and 5 on the right. If you also have a value of 37 to plot you would also put a 7 on the right. You can also tell if the data is more frequent on either side, if there are any outliers, and if there are peaks and gaps. In this data it is symmetrical, outliers at 102, peaks at 50 and gaps at 88-102.

In this plot the dots show the frequency of the value below. For example, the value 6 has 4 dots, meaning it has a frequency of 4.
