What is an outlier in a stem-and-leaf plot?

Stem-and-Leaf Plot: A plot where each data value is split into a "leaf" (usually the last digit) and a "stem" (the other digits). For example "32" is split into "3" (stem) and "2" (leaf). The "stem" values are listed down, and the "leaf" values are listed next to them. This way the "stem" groups the scores and each "leaf" indicates a score within that group.

A Stem and Leaf Plot is a special table where each data value is split into a "stem" (the first digit or digits) and a "leaf" (usually the last digit)

For Example. - in "25"
Stem = 2
Leaf = 5 

Hope this helps!
