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
My imaginary study would be to look at a pregnant mother's eating habits and see if they have any effect on a child's IQ. We could look at mothers who ate very healthy, and mothers who ate poorly when pregnant as our groups.
1) Our hypothesis would be:
Ho: The IQ of children born to both groups of mothers is identical
Ha: The IQ of children born to mothers who ate healthy is higher then those born to mothers who ate poorly
2) & 3)
The independent variable is the variable that is varied by the researcher, and the dependent variable is the response that is measured.
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 ...
