SPCE 630 Final Examapplied research - correct answer scientific study that aims to solve practical problems independent variable - correct answer The experimental factor that is manipulated; the variable whose effect is being studied. dependent variable - correct answer The outcome factor; the variable that may change in response to manipulations of the independent variable. internal validity - correct answer the degree to which changes in the dependent variable are due to the manipulation of the independent variable experimental control - correct answer Two meanings: (a) the outcome of an experiment that demonstrates convincingly a functional relations, meaning that experimental control is achieved when a predictable change in behavior (the dependent variable can be reliably produced by manipulating a specific aspect of the environment (the independent variable); and (b) the extent to which a researcher maintains precise control of the independent variable by presenting it, with drawing it, and/or varying its value, and also by eliminating or holding constant all confounding and extraneous variables. Functional Relation - correct answer The change in the DV (behavior) is causally (functionally) related to the implementation of the IV evidence-based practice - correct answer intervention procedures that have been scientifically verified as being effective for changing a specific behavior of interest, under given conditions, and for particular participants Reliability - correct answer the extent to which a test yields consistent results, as assessed by the consistency of scores on two halves of the test, on alternate forms of the test, or on retesting threats to internal validity - correct answer variables other than the planned independent variable that could result in changes in the dependent variable: history, maturation, testing, instrumentation,
