Question

Juliet conducted a survey to find the favorite type of book of the students at her school. She asked 20 students from her class what their favorite type of book is. Juliet concludes that short stories is the favorite type of book of the students in her school because 80% of the students in her class like short stories. Use at least two sentences to explain why Juliet's sample may not be valid. Make sure to use facts to support your answer.

Answer 1

The reason is because she didn't survey the school, but only surveyed her class, and to add to that It didn't say it was a random selection of students.

Juliet concludes that short stories is the favorite type of book of the students in her school because 80% of the students in her class like short stories.

That is inaccurate, she is assuming, that just because the students in her class chose short stories, she assumes the rest of the students will chose it.

Hope this helps! xx
