What is the dilemma faced by researchers regarding the three desirable qualities?
Maximizing one quality results in the reduction of the other two

Dilemmatic approach
What are the two essential components of true experiments?
Manipulation, random assignment

What do covariates do in correlational research?
Statistically control the influences of nuisance variables
