What is a stem and leaf key?
When reading a stem and leaf plot, you will want to start with the key. It will guide you on how to read the other values. The key on this plot shows that the stem is the tens place and the leaf is the ones place. Stem and leaf plots are similar to horizontal bar graph, but the actual numbers are used instead of bars.
How do you explain a stem-and-leaf plot?
A stem and leaf plot looks something like a bar graph. Each number in the data is broken down into a stem and a leaf, thus the name. The stem of the number includes all but the last digit. The leaf of the number will always be a single digit.
Why do we use stem and leaf plots?
Usage. Stem-and-leaf displays are useful for displaying the relative density and shape of the data, giving the reader a quick overview of the distribution. They retain (most of) the raw numerical data, often with perfect integrity. They are also useful for highlighting outliers and finding the mode.
What is the leaf unit?
The “leaf unit” at the top of the plot indicates which decimal place the leaf values represent. The first row of the stem-and-leaf plot of Wait times has a stem value of 8 and contains the leaf values 0, 2, and 3. The following stem-and-leaf plot shows customer wait times.
How do you read a stem and leaf?
A stem and leaf is a table used to display data. The ‘stem’ is on the left displays the first digit or digits. The ‘leaf’ is on the right and displays the last digit. For example, 543 and 548 can be displayed together on a stem and leaf as 54 | 3,8.
What are data values in a stem and leaf plot?
The stem and leaf plot is a plot used to represent numerical data by showing its distribution. Each numerical data value is split into a stem (the first digit or digits) and a leaf. The stem is the first digit or digits, while the leaf is the last digit. Each stem is listed, even if some stems have no leaves.
What does the stem term mean?
science, technology, engineering and mathematics
STEM is a common abbreviation for four closely connected areas of study: science, technology, engineering and mathematics. The fields are often associated due to the similarities that they share both in theory and practice.
How do you do a stem and leaf?
How to Make a Stem-and-Leaf Plot
- Step 1: Determine the smallest and largest number in the data. The game stats:
- Step 2: Identify the stems.
- Step 3: Draw a vertical line and list the stem numbers to the left of the line.
- Step 4: Fill in the leaves.
- Step 5: Sort the leaf data.
What are stem values?
A plot where each data value is split into a “leaf” (usually the last digit) and a “stem” (the other digits). The “stem” values are listed down, and the “leaf” values are listed next to them. This way the “stem” groups the scores and each “leaf” indicates a score within that group.
