imaginary quasi-experimental study

Design an imaginary quasi-experimental study. Then answer the following questions:

1. What is the hypothesis of your imaginary study?

2. What is/are the independent variable(s)?

3. What is/are the dependent variable(s)?

4. Briefly, how will you test your hypothesis? That is, what are the procedures you will use in your study?

5. What led you to your hypothesis; that is, what makes you think that changing the independent variable(s) will cause a change in the dependent variable(s)?

6. Now comes the fun question: Why could this study not be conducted with a true-experimental design

Our IV would be if a pregnant mother ate healthy or not

Our DV would be their baby's IQs

4) What we would do if collect a large group of pregnant woman, and ...
