2 x 4 example!

Do not use the same independent or dependent variables that are in this example

1. The Effects of Diet and Exercise on Weight Loss

2. First independent variable = diet (2 levels: group 1= no diet; Group 2= 1000 calories a day for 1 month)

Second independent variable = exercise (2 levels: group 1= exercise 1 hr per day= group 2 exercise 2 hours per day for 1 month)

3. Weight loss after 1 month
