2 major purposes of research design - correct answer 1. to provide answers to research questions
2. to control variance, insuring that the results obtained are as closely related to what is being studied
Maximincon Principal - correct answer MAXimize the variance of the variables of the substantive
research hypothesis (i.e., you want the experimental conditions to be as different as possible); to
CONtrol extraneous variables (i.e., these are independent variables that are not necessicarily related to
your study, (e.g., sex, race); and MINimize error variance (i.e., this is the fluctuation that may occur in
your results due to random events).
Variable - correct answer any phenomena or characteristic that is free to vary with at least two
conditions or levels (e.g., gender with both males and females is a variable; males alone would be a
constant)
Constant - correct answer restricted to a single state (e.g., gender is a constant if females only are used
in a study-not both sexes)
Independent Variable - correct answer presumed cause
Dependent Variable - correct answer presumed effect and vary as related to the independent variable,
usually the treatment being tested is the independent variable
Hypothesis - correct answer a proposition that is stated in a testable form
