Lecture 4 Research Design
Why Design Matters?
•3 Main types of design
•Each type of design has advantages and disadvantages
•Understanding design type allows you to ask:
oWhy did they choose THIS type of design?
oCan they really draw THOSE conclusions based on THIS type of design?

•Explore and describe
•(hard to come to generalizations because each case is unique)
2. Experimental Design
