The answers to the questions required for the design experiment above are :
- If shark attack are related to the number of elephant seals in an area, then shark attack will increase as the number of elephant seal increases
- If shark attack are unrelated to number of elephant seal in an area, then shark attack is unaffected by increase or decrease in number of elephant seal.
- The Control Group : Beaches or areas where elephant seals aren't present or period of the year when there are no elephant seal at the beach.
- The Experimental group : Beaches where varibale portions of elephant seals are found (area with high, medium or low).
- The Dependent variable : Number of shark attacks
- The Independent variable : The different number of elephant seals found.
- Data to be collected include : The number and type of elephant seals found at various beaches and the number of shark attacks recorded at the various points.
- John will be able to deduce if the number of elephant seals and number of shark attacks recorded corded are related.
