Morisha Is a Policy Researcher Who Studies Parents' Interest in Charter

Morisha is a policy researcher who studies parents' interest in charter schools.As part of her work she conducted extended interviews with parents who wanted to enter their children into charter schools for high school.While conducting her interviews,she noticed one family whose reasons were so unlike the others that she wondered whether she should even include the data in her sample.Your best advice to her would be to:

A) exclude the data because the family is such an extreme outlier; maybe they weren't really honest.
B) review the interview questions to see if they're biased in some way.
C) collect more data because this family probably isn't unique.
D) keep the data,and make sure her analysis plan accounts for a broad range of responses.
