Vocabulary:
CLOs: Analyze the data displayed on a line plot. Create a stem-and-leaf plot with a given
data set.
Line plot
Most people are familiar with bar graphs, line graphs, and circle graphs.
Here we will explain two kinds of plots that are used to visualize data.
frequency
comparing
organize
A line plot is a graph that shows _________________ of data along a number
line.
It is best to use a line plot when ____________ fewer than 25 numbers. It is a
quick,
simple way to _______________ data.
EXAMPLE
The following numbers are the result from a test taken by a class of 24 students:
16, 14, 17, 11, 14, 19, 11, 17, 12, 21, 22, 18, 11, 16, 15, 14, 18, 12, 13, 16, 17,
15, 13, 17
scale
interval
To make a line plot out of our data we determine a _________ that includes all
of the
data in appropriate ___________________. Then we _________ each number
plot
frequency
using X or other marks to show the ___________________:
statistics
A stem-and-leaf plot
distribution
in __________________, presents data in a
graphical
format to assist in visualizing the shape of a __________________.
stem
leaves
The ____________ usually consists of the digits in the greatest common place
value
of each data while the ____________ contain the other digits of each item of
data.
EXAMPLE
We return to the result from the last example:
16, 14, 17, 11, 14, 19, 11, 17, 12, 21, 22, 18, 11, 16, 15, 14, 18, 12, 13, 16, 17,
15, 13, 17
First we sort the results in ascending order:
11, 11, 11, 12, 12, 13, 13, 14, 14, 14, 15, 15, 16, 16, 16, 17, 17, 17, 17, 18, 18,
19, 21, 22
Then we plot our stem-and-leaf plot:
left hand column
The stem is found in the _________ ___________ ____________and contains
our tens digits.
right-hand column
The leaf, found in the_________ ___________ _____________, shows all the
ones digits for each of the tens and twenties.
In order to determine our original values we
simply connect our tens digits with our ones
digits.
