Question

Lucy wanted to know what percentage of students plan to attend graduate or professional schools after college, so she distributed a survey in three of her classes. Based on the results, Lucy concluded that nearly a third of college students plan to continue their education further. What is wrong with the way Lucy used the statistics from her survey?

Answer 1

Answer:

Her sample is not representative of college students as a whole

Explanation:

Lucy just distributed the survey in three of her classes and this is not encompassing enough hence cannot be used to draw a conclusion on the population. She could have gone across different sections of students in the college and make the selection such that every part is duely represented, after which she can conduct her survey.
