![]() Create a side-by-side stem-and-leaf plot of these wins and losses. The table shows the number of wins and losses the Atlanta Hawks have had in 42 seasons. Presidential Ages at Inauguration: President Construct a side-by-side stem-and-leaf plot using this data. The two following tables show the ages of presidents at their inauguration and at their death. The leaves are to the left and the right of the stems. In a side-by-side stem-and-leaf plot, two sets of leaves share the same stem. It takes some background information to explain outliers, so we will cover them in more detail later.Ī side-by-side stem-and-leaf plot allows a comparison of the two data sets in two columns. Remember that the leading values become our stems and the trailing values the leaves. Some outliers are due to mistakes (for example, writing down 50 instead of 500) while others may indicate that something unusual is happening. This example shows how to make a stem and leaf plot. When you graph an outlier, it will appear not to fit the pattern of the graph. An outlier is an observation of data that does not fit the rest of the data. A stem-and-leaf plot is a way of organizing data into a form to easily look at the frequency of different types of values. You want to look for an overall pattern and any outliers. The stemplot is a quick way to graph data and gives an exact picture of the data. ![]() Eight out of the 31 scores or approximately 26% (\frac) were in the 90s or 100, a fairly high number of As.Ģ 2 3 4 8Ġ 2 2 3 4 6 7 7 8 8 8 9Ġ 0 1 2 2 2 3 4 6 7 7 The stemplot shows that most scores fell in the 60s, 70s, 80s, and 90s.
