Can’t I just use a pie chart for everything?

2. NO!
There are many different types of graphs and they are all used to show data in a different way. DON’T just use a circle graph for everything. Let’s explore a few of the different types of graphs…

3. Plotted Points that show a relationship between data
Scatter Plots
Plotted Points that show a relationship between data

4. Scatter Plots - Find a Trend
Collection of points that have one value determining position on x-axis and a second value determining position on y-axis. (plotting a point)
EX: # of hours studying : grades
# of tumblers sold : $ raised
# of iTunes downloads : ranking on the charts

5. Displays how data changes over a period of time

What is the whole?
What are the parts?
What percentage does each part have of the whole?
Favorite lunch item

9. Shows the relative size of things
Bar Graph
Shows the relative size of things

10. Double Bar Graph Compare the size of two situations/variables

You can really compare and present more than one type of information using a double bar graph.

11. Bar Graphs – Compare Categories
Comparing quantities in different categories in both regular and double bar graphs
Amount of sugar in foods
Amount of students in clubs
Amount of electricity use

12. Similar to bar graphs, but groups numbers into RANGES
Histogram
Similar to bar graphs, but groups numbers into RANGES

13. Histograms – show results of continuous data
Age ranges, weight, times, heights, etc…

14. Which graph fits your data?
