Transcript Bar Graph - Smryna Middle School

Bell Work
8/23
• Please have out your science scenario that
you were to have created for class today. If
you do NOT have it, you will not get credit
for today’s bell work.
• Also have out the Simpson’s WS that was
homework last night.
GRAPH NOTES!!
Bar Graph
• A bar graph is best used for comparing data quickly
and easily, such as the grade distribution of students
enrolled in science class or the growth of plants in
different pots.
Line Graph
• A line graph is best used for looking at changes over
time, such as the number of bathing suits sold each
month during the year or the change in your sister’s
height throughout the year.
Steps to set-up Bar/Line Graphs
• First, set up your graphs with an x-axis and a y-axis.
The x-axis is horizontal, and the y-axis is vertical.
Y-AXIS
X-AXIS
• The x-axis represents the independent variable.
• The y-axis represents the dependent variable.
• Choose a scale for each of the axes. Select evenly
spaced intervals that include all of your data.
Steps cont.
• Plot your data on the graph.
• give your graph a title. A title tells the
reader what he or she is studying.
Pie Chart
• A pie graph is best used for showing percentages,
such as the percentage of the student body who
picked certain entrees for lunch or the percentage of
your allowance that will go toward purchasing various
things.
Practice Graph
• Determine which type of graph should be
used to create the graph using the data
below.

Create your own graph
• Create a data table of information that
another person has to create a graph for.
This will be your bellwork tomorrow using
each others data tables to create their
graphs.
