Quantitative Research
Attempts to quantify key variables and relate them
Variables are manipulated in some way (Called a treatment)
Results are measured and analyzed statistically
Goal is to identify cause-and-effect relationships
Notes:
Quantitative research is an attempt to get at the numbers.
These studies are generally “very scientific” and conducted in controlled ways.
Variables are manipulated to determine the optimum level
Often filled with statistical analysis.
Models may be tested to determine main effects and interactions
Back to our online manuals example:
Is there a relationship between experience with online documentation and how quickly users can solve a problem? Maybe your online manual is so easy that novices are just as quick with them as more experienced users.
The goal is to identify cause and effect relationships
Strengths - Very scientific
Weakness - Results are sometimes artificial and narrow in scope
