LIst the non-scientific and scientific ways to acquire knowledge
-tenacity=accept common knowledge as truth
-reason and logic
-scientific method-a method used to collect and evaluate data
List and describe the criteria for scientific investigation
systematic empiricism=the gathering of knowledge from either experience or observation

-public verification=the study must be replicated or verified by others.

test hypothesis=review literature and design a study

analyze results and draw conclusions=develop stats and report whether hypoth was supported

report findings=write up research

correlational research=goal is to look for relationships between variables. (no manipulation and no causation).

Experimental research=goal is to manipulate one variable, and look for changes in the other variable.

Quasi-Experimental research=goal is to make use of a naturally-occuring variable.
Why is effect size calculated?
To assess how strongly the variables under investigation are related to the responses.
systematic variance divided by ____=effect size
total variance
standard deviation=____.
(x sub i -x-bar) ^2 divided by (n-1).
systematic variance divided by total variance= ___ ___.
effect size.
