Random Assignment
To minimize the chances that an unintended variable influences the results, subjects must be assigned randomly to different treatment groups. Random assignment is used to ensure that any preexisting differences among the subjects do not impact the experiment.

Which of the following is the best definition of illusory correlation?

In a true experiment, the effect of an intervention is tested by comparing two groups. One group is exposed to the intervention ( the experimental group , also known as the treatment group) and the other is not exposed to the intervention (the control group).
Which technique is used to help reduce experimenter bias?
The double-blind procedure helps minimize the possible effects of experimenter bias. 2 Such biases often involve the researchers unknowingly influencing the results during the administration or data collection stages of the experiment.
How can we minimize experimenter effects?
Another technique for the control of experimenter effects is to minimize contact between the experimenter and the participant. The less exposure a subject has to experimenters, the less likely it is that cues from the experimenter will be “picked up” by the respondent.
What is the principal disadvantage of the experimental approach?
What are the 2 major disadvantages of the experimental method? ... Experiments are often artificial and doubts arise about the applicability of the findings .
Which procedure helps to ensure that the participants?
Random assignment helps ensure that members of each group in the experiment are the same, which means that the groups are also likely more representative of what is present in the larger population.
What is hindsight bias in psychology?
