This stemplot is read as follows: the stem is the tens digit and each digit in the "leaves" section is a ones digit. Put them together to have a data point. In the particular case there are 15 data points therefore the median is 79. Thus the first quartile is 69 and the third quartile is 87.

Moreover, how do you read a stem and leaf plot?

Stem-and-Leaf Plot. 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.

Additionally, do you repeat numbers in a stem and leaf plot? The stem-and-leaf plot only looks at the last digit (for the leaves) and all the digits before (for the stem). So I'll have to put a "key" or "legend" on this plot to show what I mean by the numbers in this plot. The ones digits will be the stem values, and the tenths will be the leaves.

Similarly, how do stem and leaf plots work?

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).

What is a line plot in math?

A line plot is a graph that shows frequency of data along a number line. It is best to use a line plot when comparing fewer than 25 numbers. It is a quick, simple way to organize data. Example.

What is the key to a stem and leaf plot?

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.

How do you do a stem and leaf plot with thousands?

Tips on how to draw a stem and leaf plot
  1. 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.
  2. Draw a line to the right of these stems.
  3. On the other side of the line, write down the ones (the last digit of a number).

What does Leaf Unit mean?

For each row, the number in the "stem" (the middle column) represents the first digit (or digits) of the sample values. The "leaf unit" at the top of the plot indicates which decimal place the leaf values represent.

How do you know if a stem and leaf plot is symmetric?

When data are skewed, the majority of the data are located on the high or low side of the graph. Skewness indicates that the data may not be normally distributed. Often, skewness is easiest to detect with a histogram or a boxplot. The following stem-and-leaf plots are skewed.

What are the points on a scatter plot called?


Sometimes the data points in a scatter plot form distinct groups. These groups are called clusters.

What are stem and leaf plots best used for?

1 Answer. 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.

How do you create a stem and leaf plot in Word?

Click the table to open the Table Tools tab at the top of the work area. Click the Design tab if it is not enabled. Click the “Plain Table 4” option in the Table Styles section of the ribbon. This takes the borders off the grid and leaves you with just the stem and leaf plot data.

When would you use a stem and leaf plot?

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.

When would you use a stem and leaf plot in real life?

Stem and leaf plots are useful in some cases because you can see where the bulk of scores lie. In the above graph, most scores were in the 20s or 60s. Bar graphs also show this information, but the advantage the stem and leaf plot have is that you can see all of the scores (other charts usually show just totals).

When would you use a histogram?


The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins. Bar charts, on the other hand, can be used for a great deal of other types of variables including ordinal and nominal data sets.

What's the mode of a number?

The mode of a data set is the number that occurs most frequently in the set. To easily find the mode, put the numbers in order from least to greatest and count how many times each number occurs. The number that occurs the most is the mode!
