3. Data Tables
Data are the facts, figures, and other evidence gathered through observation.
A data table provides an organized way to collect and record observations
After the data are collected, they need to be interpreted or explained. Graphs are used to do this.

8. Types of Graphs
Line graphs
Bar graphs
Circle graphs

9. Line Graph
Line graphs are used to display data to show how one variable (the responding variable) changes in response to another variable (the manipulated variable)

10. What to include on a graph
Boiling Time of Water by Volume
1. Draw the axes
2. Label the axes
3. Create a scale
4. Plot the data
5. Draw a line
6. Add a title 40 30
Boiling Time (min) 20 10
dependent Variable
500
1,000
1,500

Volume of Water (mL)
Independent Variable

11. Bar Graph A bar graph is used to show comparisons between data
All bar graphs have vertical and horizontal axes.
Bars can be displayed in a vertical or horizontal format
The X-axis is the manipulated variable
The Y-axis is the dependent variable.

17. 2. Set up the proportion, then cross multiply
1. use a compass to draw a circle. Mark the center with a point. Then draw a line from the center point to the top of the circle.
2. Set up the proportion, then cross multiply
your time here X =
Text
24 hrs
360 O
Step 1 insert your time
Step 2 cross multiply X
24hrs =
8x360 =24X O O
Step 3 divide
360 x 8 = 2880
24X
= 120
