Patrick wanted to find out which spice would be best for increasing the amount of crabby patties sold.

Which was the independent variable?

• The number of patties sold
• The spice added
• How long each patty was cooked for
• Adding no spice to one patty

Patrick wanted to find out which spice would be best for increasing the amount of crabby patties sold.

Which would be a constant?

• The number of patties sold
• The spice added
• Making sure to cook each patty for 5 minutes
• Adding no spice to one patty

Patrick wanted to find out which spice would be best for increasing the amount of crabby patties sold.

Which was the dependent variable?

• The number of patties sold
• The spice added
• How long each patty was cooked for
• Adding no spice to one patty

Patrick wanted to find out which spice would be best for increasing the amount of crabby patties sold.
Patrick decided to not add any spice to one type of crabby patty sold.

This would be an example of a ...

• Dependent Variable
• Independent Variable
• Constant
• Control

Patrick wanted to find out which spice would be best for increasing the amount of crabby patties sold.
What would be the best statement of the problem for Patrick's experiment?

• We wanted to find out if adding spice and better quality meat will increase the amount of burgers sold.
• We wanted to find out if adding onion powder will increase the amount of burgers sold.
• We wanted to find out which spice would be the best.
• We wanted to find out how to increase the amount of burgers sold.

Patrick wrote the following for statement of the problem.

We wanted to find out if adding spice and better quality meat will increase the amount of burgers sold.

Is this a good statement of the problem.  Why or why not?

• Yes, because includes the independent and dependent variable.
• No, because it includes two independent variables.
• No, it is too vague about the dependent variable.
• No, because it identifies a variable that is not tested.

Patrick wrote the following conclusion based on his results.
The onion powder which sold 25 patties sold the greatest number of crabby patties compared to pepper which sold 22 patties, or no spice added which sold 22 patties. 

Is this a good conclusion, why or why not?

• Yes,  the analysis is correct and includes data to support it.
• No, the analysis is not correct.
• No, the conclusion included no data to support it.
