Graphing Challenge Review

What are the 5 requirements for making an accurate graph?

Answer explanation

5 requirements for a graph:

1. 1. Title w/ IV and DV

2. 2. IV on x-axis; DV on y-axis

3. 3. Axis labels (with units!)

4. 4. Even scale

5. 5. Correct type of graph

In what circumstance would a bar graph be needed? Line graph?

Answer explanation

Bar graphs are used when the independent variable are separate groups that are being compared. For example, bar graphs can be used to compare the amount of energy stored in different trophic levels.

Line graphs are used when the independent variable is something continuous like time, temperature, and pH. For example, line graphs can be used to track the amount of rain that falls each month.

Create an experimental design with a clearly labeled control group, experimental group, independent variable, and dependent variable.
