Answer:
the bystander effect.
Explanation:
The bystander effect: The term bystander effect is also referred to as bystander apathy or bystander intervention. This is one of the psychological phenomenon which explains that an individual has got the least tendency of helping the other person in an emergency when there are other person present in the given situation competitively when the individual is alone.
Hence, in an emergency, the observers are more likely to intervene if there are no other witnesses present at the moment.
In the question above, Mrs. Blake's experience best illustrates the bystander effect.
In a procedure called random assignment, participants are placed in experimental conditions on the basis of chance, thus minimizing biases or preexisting differences in the groups.
Basically, the experimental condition is once the man of science manipulates the variable to assess its result on the variable. Below the experimental conditions, the participants receive experimental treatment whereas the participants within the control group don't receive any treatment.
Random assignment helps make sure that members of every group within the experiment area unit identical, which implies that the teams are doubtless a lot of representative of what's present within the larger population.
