1. Graphing

2. Why use a graph? To Analyze Data
Graphs are used to organize data
Graphs are used to easily and quickly interpret data

3. Types of Data
Qualitative- information that describes color, odor, shape or some physical characteristic
Quantitative data- numerical information

4. Types of Graphs
Circle graph (pie chart)
Bar graph
Line graph

5. What each graph needs 1. Determine a Title for the graph
2. Identify manipulated and responding variables
3. Determine the increments needed for the axes. Remember increments must be equal.
4. Create a key or label axes with units
5. Create the graph from data

6. Bar Graph Compares quantities and categories
What is missing from this graph?

7. Bar Graphs

8. Circle Graph (Pie Chart)
Useful when percentages need to be represented
Use a pie chart when representing parts of a whole (100%)

10. Line Graphs Compare relationships between two variables
What are the 2 types of variables?
On which axis is each located?
Determine if the relationship is direct or inverse.

11. Line Graphs

13. M & M’ s
Create a data table to record color and numbers of each color of m & m’s.
Identify the different colors of M & M’s and count the number of each color.
Create a bar graph using space on your graph paper.
Remember the things that every graph or chart needs.

14. M & M ‘s
Convert the data collected from your bar graph to percentages (part / total x 100)
Construct a Pie Graph using the results of your calculations
Include all parts of a graph

15. M & M’s
Count the total number of M & M’s and begin with an EVEN number
Create a table to record time and number of M & M’s remaining
Every 15 sec eat half of the M & M’s
Remember to record how many M & M ‘s remain each time
Continue eating the M & M’s until one remains
Create a line graph using your time and number of M & M’s eaten.
