How do you make a stem-and-leaf plot?
Tips on how to draw a stem and leaf plot On the left hand side of the page, write down the thousands, hundreds or tens (all digits but the last one). These will be your stems. Draw a line to the right of these stems. On the other side of the line, write down the ones (the last digit of a number).
What does leaf mean in math?
more A plot where each data value is split into a “leaf” (usually the last digit) and a “stem” (the other digits). For example “32” is split into “3” (stem) and “2” (leaf). The “stem” values are listed down, and the “leaf” values are listed next to them.
What do stem and leaf plots show?
Stem-and-leaf plots are a method for showing the frequency with which certain classes of values occur. You could make a frequency distribution table or a histogram for the values, or you can use a stem-and-leaf plot and let the numbers themselves to show pretty much the same information.
What is the key in stem and leaf?

What is leaf unit 10?
Leaf Unit or Key That’s simple because a leaf of 1 = 1, 2 = 2, and so on. If the unit had been 10, the leaves would’ve been 10, 20, 30, etc. Or, if it had been 0.1, leaves would represent 0.1, 0.2, and so on. This unit depends on how you or your software rounds the data.
What is sample size in stem and leaf?
Sample size (N) The sample size can affect the appearance of the graph. The sample size is displayed at the top of the stem-and-leaf plot. In the previous example, the sample size is 50 (N=50). Because a stem-and-leaf plot represents each data value, it is best when the sample size is less than approximately 50.
What can you learn from a stem-and-leaf plot?
A stem-and-leaf plot is a type of graph that is similar to a histogram but shows more information by summarizing the shape of a set of data (the distribution) and providing extra detail regarding individual values.
How does the stem-and-leaf plot shows the distribution of these data?
A stem and leaf plot (sometimes called just a “stem” plot) is a display that organizes data to show its shape and distribution. In a stem and leaf plot, each data value is split into a “stem” and a “leaf”. The “leaf” is usually the last digit of the number and the other digits to the left of the “leaf” form the “stem”.
Can Excel make stem and leaf plots?
Does Excel have the ability to make these plots? Excel is a very powerful tool when it comes to visualising sets of raw data. It can make bar charts, line charts, scatterplots, sunbursts, combinations of these together – but there is no built in function to create a Stem and Leaf Plot in Excel.
