Stem and Leaf Plot
By Turtlediary
A stem and leaf plot shows a large amount of data in a clear way by listing it in order of place value. A stem and leaf plot is generally used when data has multi-digit numbers. In this kind of plot, the ones digit of each number in the data is separated from the other digits. The plot has two columns. The first column, called the “stem”, lists all of the digits in the tens place and beyond, in order. A vertical line divides the stem from the “leaves” (the second column). This second column shows the ones place of each number in the data, also in order. Every number in the leaf column represents a number from the data. Its ones place is in the leaf, and the tens place and beyond are in the stem.
