Web3.5 - Bias, Confounding and Effect Modification. Consider the figure below. If the true value is the center of the target, the measured responses in the first instance may be considered reliable, precise or as having negligible random error, but all the responses missed the true value by a wide margin. A biased estimate has been obtained. WebThe answer is yes, and this is the interaction effect. It is possible that levels of the IVs interact and affect the DV differently than each by itself. For example, maybe there is no effect when participants get only 1 mg of the sleep drug and 12 oz of beer. But when you give them 1 mg of the sleep drug and 36 oz of beer there is an effect.

Although commonly thought of in terms of causal relationships, the concept of an interaction can al…
WebIn an interaction (a true synonym for a moderator effect--not something different), there is no need for one predictor to influence the other or even be correlated with the other.
