FutureStarrA Stem and Leaf With Decimals
Leaves have decimal numbers like 4. 5, 5. 5, 5. 4, and 7. 4. Stem numbers like 3, 5, 8, are what the leaves are attached to.
Stem and leaf plots are a valuable way of organizing your data, and determining how many data points with a particular ones, tens, or hundreds digit you have. You can use stem and leaf plots to organize decimals much the same way that you would use stem and leaf plots to organize whole numbers. Since stem and leaf plots are not traditionally used to organize decimal numbers, you will need to create a key that makes it clear to your readers that you are organizing decimals.
I found some data on 49 earthquakes that causes significant damage in California. (This comes from a textbook without a reference so it may not be real data.) The numbers are the Richter Scale measurements of the quakes and range from 5.3 to 8.3. I decided to split the data into groups 5.0 to 5.4, 5.5 to 5.9, 6.0 to 6.4 and so on and present it in a stem and leaf plot. Here is my plot (Source: mathcentral.uregina.ca)
A stem and leaf plot is a special table with two columns. The main idea is to divide each data point into a ‘stem’ and ‘leaf’. The left – side column is the ‘stem’ and the right – side column is the ‘leaf’. The ‘stems’ are the digits that given numbers have in common, while the ‘leaves’ are what differs them. For instance, the S – L plot for the previous example would be:
A stem and leaf plot is a table used to display data. The 'stem' is shown on the left side of the table and shows the first digit or digits of data values. The 'leaf' is shown on the right side of the table and shows the last digit of the data value. For example, 443 and 447 can be shown together on a stem and leaf plot as 44 | 3,7. 44 is shown under a column of the stem and the last digits of both numbers, 3 and 7, shown under the leaf column.
