Factors that contribute to measurement error
Factors that contribute to measurement error include
Verification
Verification: One of three components of the experimental reasoning, or baseline logic, used in single-subject research designs; accomplished by demonstrating that the prior level of baseline responding would have remained…
Trend
Trend: The overall direction taken by a data path. It is described in terms of direction (increasing, decreasing, or zero trend), degree (gradual or steep), and the extent of variability…
Parametric Analysis
Parametric Analysis: An experiment designed to discover the differential effects of a range of values of an independent variable. Applied Behavior Analysis (2nd Edition) An easy way to understand this…
Threats to Validity
Threats to validity include mortality, maturation, experimenter bias, regression to the mean, selection, reactive measures, repeated measures, history and instrumentation. Applied Behavior Analysis (2nd Edition) History: A major holiday season…
Dimensional qualities of behavior
The dimensional qualities of behavior from which all behavioral measurements are derived include temporal extent, temporal locus, and repeatability. Temporal Extent: refers to the fact that every instance of behavior…
Operant Behavior
Operant Behavior: Behavior that is selected, maintained, and brought under stimulus control as a function of its consequences; each person’s repertoire of operant behavior is a product of his history…
