How do we determine whether one event causes another event: (does a cause b?) Is there a correlation between an iv and a dv: the causal relationships between variables in behavioral science are probabilistic, temporal priority. If event a occurs before event b, then a might be causing b. Experimental condition: refers to the specific situations that are created within the manipulation. In one-way designs, these are called the experimental conditions: a one-way experimental design. Equivalence can be created through: between-participants designs each level of the experiment or experimental conditions, repeated-measures designs, also called within-subjects design, random assignment. Random assignment to conditions with different but equivalent participants in with the same people in each of the created.
