In a recent article, the author states that 71% of adults do not use sunscreen. Although 71% is a large percentage, explain why it could be misleading. As you answer the questions above, identify what types of misrepresentation or misuse have been demonstrated by referring to the bold blue headings in the “Chapter 12 Supplement” (e.g., Suspect Samples, Asking Biased Questions, Misleading Graphs, etc.).

Answer 1

You need a representative sample of all adults, and you need to ask about use of sunscreen in a non-judgemental way. You also need to caqrefully define "use".

We do not have the benefit of your "Chapter 12 supplement" to help answer the question. Many adults use sunscreen purchased by others, and only occasionally.

I use it about once a year. I don't buy it... my wife does. Does that make me a non-user?

Answer 2

Create a math formula showing that if 71% of adult use sunscreen and 71% is a large number how many use or do not use sunscreen?
