A leaf unit of 1 implies a binning on the stem in 10s, that is, 20, 30, 40, all the way to 110 and 120. For example the smallest value in the sample is 27. This is read in the Stem-and-Leaf plot on the first row by combining the stem digit 2 and the leaf digit 7.
A side-by-side stem-and-leaf plot allows a comparison of the two data sets in two columns. In a side-by-side stem-and-leaf plot, two sets of leaves share the same stem. The leaves are to the left and the right of the stems. The two following tables show the ages of presidents at their inauguration and at their death.
A stem and leaf plot can help you quickly identify how frequently data occur. For example, a quick look at the figure above will show that the number 34 occurs most often. It can also help you identify quickly the least and the greatest data value. Example #2: This time, the data is already in order. 104, 107, 112, 115, 115, 116, 123, 130, 134 ...
A stem-and-leaf plot provides a convenient way to display the distribution of these data. In a stem-and-leaf graph, we separate the digits of each data point into the right most digit vs. the rest, so, for example, the 1s place becomes the “leaf,” and the rest of …
A stem-and-leaf plot, on the other hand, summarizes the data and preserves the data at the same time. The basic idea behind a stem-and-leaf plot is to divide each data point into a stem and a leaf. We could divide our first data point, 111, for example, into a stem of 11 and a leaf of 1. We could divide 85 into a stem of 8 and a leaf of 5.

Example: 32 is split into 3 (stem) and 2 (leaf). More Examples: Stem 1 Leaf 5 means 15. Stem 1 Leaf 6 means 16. Stem 2 Leaf 1 means 21. etc. The stem values are listed down, and the leaf values go right (or left) from the stem values. The stem is used to group the scores and each leaf shows the individual scores within each group. Get Details
Following are the characteristics of a stem and leaf plot –. The stem is the first digit or digits, while the leaf is the last digit. The stem and leaf plot is used when your data is not too large, i.e. about 15-150 data points. The stem and leaf plot is drawn in a table with two columns.
In other words, the decimal point is 1 digit after the leaf. Notice that the leaf is a single digit. That means, you need to add a 0 after each leaf. For example, the first entry has a stem of 0 and leaf of 4. That means that the shortest river is 40 miles. The next river has a stem of 2 and a leaf of 0. That means, it is 200 miles long.

Oct 26, 2012 The most common way to do this is for the split stems to group leaves 0-5 in the first section and the 6-9 leaves in the second section. Take a look at the picture below: Note that both plots are equal. They represent the same data set. However, you will see that the split stem and leaf plot separates each stem into two stems.
Sep 14, 2016 All leaves are sorted ascending to the right All stems are sorted ascending down Has only numeric characters (besides the separator |) You do not have to deal with numbers that have fractional parts. You may approve or reject extra leading zeros in the stems, but a blank stem is not allowed. There will be at least one value.

The stem and leaf plot is a plot used to represent numerical data by showing its distribution. Each numerical data value is split into a stem (the first digit or digits) and a leaf. The stem is the first digit or digits, while the leaf is the last digit. The stem and leaf plot is used when your data is not too large (about 15-150 data points).
The stem and leaf separator are full of the latest and most advanced technological features that make farming extremely easy and efficient. The stem and leaf separator are made from strong and durable materials that ensure maximum productivity on the farm for a long period of time. The stem and leaf separator employ high-end inventions that ...
The stem is not always a single digit or the first digit of the number. As an example, if you are working with a number with 4 decimal digits, the stem could be the first three decimal digits and the corresponding leaf the fourth, as long as you indicate how digits far is the decimal point from the right of the separator.
The stem-and-leaf plot only looks at the last digit (for the leaves) and all the digits before (for the stem). So I'll have to put a key or legend on this plot to show what I mean by the numbers in this plot. The ones digits will be the stem values, and the tenths will be the leaves. Properly, every stem-and-leaf plot should have a key.
This example has two lists of values. Since the values are similar, I can plot them all on one stem-and-leaf plot by drawing leaves on either side of the stem I will use the tens digits as the stem values, and the ones digits as the leaves. Since 9 (in the Econ 101 list) has no tens digit, the stem value will be 0 .
