I Already looked at that i still dont understand
http://www.khanacademy.org/math/pre-algebra/pre-algebra-math-reasoning/pre-algebra-stem-leaf/v/u08-l1-t2-we3-stem-and-leaf-plots
Just one question not being rude anyway are you really a teacher
Yes, I'm a retired teacher. I taught for 32 years.
Ohhhhh Okay can you walk through this problem plz
From Math is Fun:
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). Like in this example:
Example:
"32" is split into "3" (stem) and "2" (leaf).
1
2
3
4
5
6
7
8
9 - 1 - 2 - 4 - 5 - 7 - 7 - 9
is ms.sue right
To construct a stem-and-leaf plot of the data, follow these steps:
Step 1: Understand the stem-and-leaf plot
A stem-and-leaf plot is a visual representation of numeric data that shows the distribution of values. Each value is split into two parts: the stem (the leading digit(s)) and the leaf (the trailing digit(s)). This plot can be useful for organizing and visualizing data.
Step 2: Identify the stems and leaves
In this case, the stems will be the tens digits (e.g., 6, 7, 8, 9) and the leaves will be the ones digits (e.g., 4, 8, 9). The data given is already in percentage form, so the stems will be the tens digits of the percentages.
Step 3: Construct the stem-and-leaf plot
Arrange the stems in ascending order and write them vertically in a column. Then, next to each stem, list the corresponding leaves.
Stem | Leaves
-------------
6 | 4
6 |
7 | 9
8 | 8, 8
9 | 1, 2, 4, 7
Step 4: Interpret the stem-and-leaf plot
Looking at the stem-and-leaf plot, you can see the distribution of microwave ownership percentages in different countries. For example, the stem 6 with the leaf 4 represents Argentina with 97% microwave ownership. The stem 7 with the leaf 9 represents Belgium with 93% microwave ownership, and so on.
The completed stem-and-leaf plot for the given data is:
6 | 4
6 |
7 | 9
8 | 8, 8
9 | 1, 2, 4, 7
This plot allows you to easily visualize the distribution of microwave ownership percentages in different countries.
