Question

Identify the stem of the following number: 231.
A. 1
B. 2
C. 3
D. 23

Answer 1

stem = 23
leaf = 1

Answer is choice D

The leaf is always a single digit because you can have multiple leaves without any separating mark. If you have something like "123" on the leaf column, then that means you have three leaves of 1, 2 and 3 which correspond to the same stem.
