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 group in a true experiment gets 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?

psychological phenomenon that allows people to convince themselves after an event that they accurately predicted it before it happened

It improves performance on easy tasks and hinders a person’s performance on difficult tasks
.
Which of the following is the best example of illusory correlation?
An illusory correlation happens when we mistakenly over-emphasize one outcome and ignore the others. For example, let’s say you visit New York City and
