Experimental Design & Graphing

Research question: does the distance a person kicks a soccer ball effect how well they will do on their math test.  What is the dependent variable?

• How far they kick the soccer ball
• who the person is
• how well they do on the math test
• Type of soccer ball.

When experimenting with the growth of a plant, a scientist uses three (of the same type of) plants, two different fertilizers, equal light, and equal water. What type of variable is the fertilizer?

• Dependent
• Independent
• Control
• Constant/

  standardizing

What would the INDEPENDENT variable be in an experiment testing which types of paper airplane goes furthest?

• the paper used
• the type of paper airplane
• the distance of each plane's flight
• how hard the plane is thrown

A summary of the experiment that includes whether or not the hypothesis was.

• Hypothesis

• Results

• Conclusion

• Independent Variable

The component of an experiment that is used for comparison or as a reference point - it is usually the group under "normal conditions."

• Control Group
• Experimental Group
• Constants

• Data Group

What are all the things that are kept the same in an experiment?

• controls
• data
• constants
• independent variables

What are the number of times each group within the independent variable groups is tested?

• constants

• control

• trials

• dependent variable

The type of variable that responds to the experiment and is what you measure to determine if your hypothesis is true.

• Independent

• Dependent

• Control

• Constant

The type of variable that you change or manipulate in an experiment.  It is what you are testing.

• Independent
• Dependent
• Control

The purpose of the control group is:

• Used for comparisons
• Application of the I.V.
• Application both the I.V. and D.V.
• Application of all constants.
