Question

You got a test grade of 25/30 on the most recent assignment, after that you believe that you had always got that same grade on assignments for that class. Which bias applies here?

a.) Representativeness heuristic
b.) Framing effect
c.) Anchoring
d.) Primacy effect
e.) Recency effect

Answer 1

The representativeness heuristic is the bias in play when a student assumes future grades will match a past grade of 25/30, generalizing from one instance instead of considering the probability of different outcomes.

Step-by-step explanation:

The bias applicable in this case is the representativeness heuristic. This bias involves using a single example to make broad generalizations, which in this context means assuming that all future grades will also be 25/30 just because one test grade was. The representativeness heuristic is a mental shortcut that relies on similarity to past experiences rather than statistical analysis, leading one to erroneously expect the same result without considering variation in outcomes or actual probability.
