Lecture 4 Research Design
Part 1
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?
Three Kinds of Design
Case Study
Experimental
Quasi-experimental
1. Case Study
Focus on a particular event, situation, or person
Explore and describe
(hard to come to generalizations because each case is unique)
2. Experimental Design
2 randomly selected groups
oTreatment Group: x happens
oControl Group: x doesn’t happen
3. Quasi-Experimental Design
The basic idea
Select a number of people (or objects)
Divide them into groups based on something that interests you
See if those groups are different from each other
