Document Summary

The stem and leaf plot on minitab resembles any stem-and-0 leaf plot that you would otherwise draw out on your own. The only difference is the count bar which is located at the far left, under c, of the. This count bar simply just counts the amount of data. The leaf unit is the value in which the leaves actually are. For this specific stem-and-leaf plot, the prior example works perfectly. Let say we are working with the fifth row: 6|1, 6|2, 6|2, 6|4. Instead of the values being 61, 62,62, 64, the values change to 610, 620,620,640. Because you now place the leaf where the one is in the unit. So, if the leaf unit was 0. 001, then the values would change to 6. 001, 6. 002, 6. 002, 6. 004. Example: suppose that scores on a quiz for n =7 students in a class are: 91, 79, 60, 94, 89, 93, 86.
