PSYB01H3 Study Guide - Regression Analysis, Internal Validity, Dependent And Independent Variables
Document Summary
In a group design: we expect the treatment group to have different scores than the control group after the intervention, random assignment controls for threats to internal validity b. Cyclical: a trend that is accelerating over time with regular increases and decreases. Direct replication: first stage of a three sequential replication strategy used to enhance the external validity of a single subject design (generalizabiity) proposed by barlow and hersen. Duration: refers to the length of time an event or some symptoms lasts, usually measured for each occurrence of the event or symptom. If behavior happens only periodically, the counts will not be meaningful. Level: the amount or magnitude of the target variable, has the amount of the target variable changed from the baseline to the intervention period, changes in level are typically used when the observations fall along relatively stable lines.
