Ariel wants to find out the most popular theme for spirit week at school. she cannot decide between two methods. option 1: she will poll each student who leaves the gym after sports practice option 2: she will randomly poll three students from each first-period class which statement about the methods is true? a. option 1 is biased b. option 2 is biased c. neither is biased d. both are biased

Option 1 says poll each student who leaves the gym after sports practice . It means she will just poll each student leaving the gym , So it will be a biased method for selecting , because the students from Sports cannot be the representative of all students , it will not be fair for other students.

Option 2 says she will randomly poll three students from each first-period class. Selecting randomly is again an unbiased method , because randomly she can select anyone , without being biased to anyone.

Hence , neither of the method is biased.

Option A is correct, first option is BIASED
