Question

Twenty percent of the students at your university are in a sorority or fraternity. You see that many of the students in your class of 200 students are wearing shirts with Greek letters on them. You conclude that half of the students are in a fraternity or sorority. Of what bias are you possibly guilty?

Answer 1

Answer: Insensitivity to prior probabilities.

Explanation: In a bid to make inference based on a given data or information, people may tend to base their conclusion on representativeness. In the scenario above, I concluded that half of the students in my class of 200 are in a fraternity or sorority. However, the baseline probability was that 20% of students in the university belong to a fraternity or sorority. Here, I have used the baseline probability to make inference or guess the probability that students who wore shirt with Greek letters on them belonged to fraternities or sororities even though no description was given about students in my class.

Answer 2

Answer: Insensitive to prior probabilities

Explanation:Being insensitive to prior probabilities means you no longer consider what existed before these two groups , you neglecting all of that and assuming that since they are these groups now this means everyone is in them.
