Lecture #9 - 9/18

individuals studied in an experiment subjects
any specific experimental condition applied to the subjects; everything you're getting treatment
variable that measures outcome or result of a study; what you're trying to measure response variable (dependent variable)
variable that we think explains or causes changes explanatory variable (independent variable)
variable that has important effect on variables in the study, but isn't one of the explanatory variables studied; "behind the scenes" lurking variable
when effects on a response variable cannot be distinguished from each other; either explanatory or lurking confounding
dummy treatment with no active ingredients (common for medical experiments) placebo
response of the patients to placebo placebo effect
comparing effects of two or more treatments by randomly assigning subjects to the different treatment groups randomized comparative experiment
observed effect so large it would rarely occur by chance; don't believe it would happen by accident statistical significance
