Because 10 of those students failed the test, which accounts for almost half of the class of 22 students, the teacher might need to try a different method that the failing group of students could understand. The stem and leaf plot retains the original data item up to two significant figures unlike histogram. The median is at (22 + 22)/2 = 22 and is marked by a box. Skewed displays show a tendency for the data to lean towards 1 side (either positive or negative). The stem column is usually located to the left of the leaf column. To see a description of this dataset, type ?rivers. The data are to be interpreted and questions based on it are to be answered in the make and interpret plot pages. A Stem and Leaf Plot is a special table where each data value is split into a "stem" (the first digit or digits) and a "leaf" (usually the last digit). Stemplots are also called stem and leaves plot as there is one step with largest place value digits on the left and at leaf (ves) to the right. Properly, every stem-and-leaf plot should have a key. This example shows how to make a stem and leaf plot. The stem-and-leaf plot only looks at the last digit (for the leaves) and all the digits before (for the stem).

Stem-and-leaf plot is used to graphically represent a small set of data measured in an interval-ratio scale. Site Navigation. Otherwise, you would have a long list of marks to sift through and analyze. Divide 30 by two, yielding 15, count either up from the lowest temperature of 50 or down from the highest temperature of 87 until you get to the 15th number in the data set, which in this case is 70.

A Stem and Leaf Diagram, also called Stem and Leaf plot in R, is a special table where each numeric value split into a stem (First digit (s)) and a leaf (last Digit). A stem and leaf plot organizes data by showing the items in order using stems and leafs.The leaf is the last digit on the right or the ones digit.The stem is the remaining digit or digits. You can also see that the Sharks and the Tigers tied for the highest score: a 59. This data is arranged by place value where the digits in the largest place are referred to as the stem, while the digits in the smallest value or values are referred to as the leaf or leaves, which are displayed to the right of the stem on the diagram.
