A stem and leaf plot is a table of values. The arrangement can give a picture of the distribution of values. Here is the leaf plot of 20 values using the following R command.
numbers <- c(19, 37, 5, 12, 15, 32, 27, 35, 23, 22, 28, 34, 31, 12, 48, 31, 31, 28, 43, 3)
stem(numbers) The decimal point is 1 digit(s) to the right of the |
0 | 35
1 | 2259
2 | 23788
3 | 1112457
4 | 38There are five stems, 0, 1, 2, 3, and 4, listed one over another. The column on the right contains the leaves arranged from left to right.
How to read:
Take the first stem, 0. There are two numbers on the right, 3 and 5. That means the set has values of 3 (03) and 5 (05).
