Credentialed people a lot more, and this resulted in more assessment of role. Manipulate one variable (independent variable), and see its effect on the other variable you"re measuring (dependent variable) while controlling for as much as possible, or else a confounding/extraneous variable may be causing the change in the dependent variable. Quasi = closest you can get to ideal conditions considering you"re dealing with the real world. Random selection is when each individual in the population as an equal chance of participating in the study.
