Quizplus · Accepted Answer

The poster represents a demand characteristic bias, as it is a cue that may lead participants to alter their behavior in a certain way (i.e. not drinking alcohol during pregnancy) regardless of their true beliefs or actions. The poster is not representative of researcher bias as it does not appear to manipulate the data collection process itself. There is no evidence of participant bias or statistical bias presented in the scenario.
