Stem and Leaf Plots A stem and leaf plot is a graph that splits a number into two parts called a stem and a leaf. The stem includes all but the last digit of the number. The leaf is the last digit. Let's consider the following numbers and identify the stems and the leaves. Raw Data 342 Now let's look at a stem and leaf graph. 713 9.4 29 Key 113=13 1714=1.74 519 = 5.9 Stem 34 When we read stem and leaf charts it is important to use the key, which informs us how we should interpret the number. For example, if the key says 311= 3.1 we know that the last digit should be in the tenths place. Try using the keys provided in the table below to interpret the raw data. 9 9 Leaf 2 Stem Leaf Raw Data 23 1 5 4 3 6 231 Now let's look at a stem and leaf graph. Title 012379 1 455566 2 557888 566 3 4 50 Key: 31 means 31 The stems are in numerical order (vertically) on the left side of the line. The leaves are on the right side side of the line and are in numerical order (horizontally). The leaves are separated by a space, but notice no commas are used. The first row of the stem and leaf chart above is 0 1 2 3 79. The key shows that 3 | 1 = 31, so we can interpret the raw data from the first line to be 1, 2, 3, 7, and 9. (Note: 01=1). There are five raw data values in the ones place value. The second row is 1 | 455566. There are six raw data values in the teens. What are the raw data values?

Notice that there is a 4-stem even though there are no raw data values in the 40's. The stems should start with the stem of the smallest data value and include every integer up to the stem of the largest data value. Optional Video: What is a Stem and Leaf Plot?
