Can you assist me, in your own words, in setting up a full statistical and word explanation for the following:
a. In an ad for moisturizing lotion, the following claim is made: '..it's the #1 dermatologist recommended brand.' What is misleading about the claim?
b. In a recent article, the author states that 71% of adults do not use sunscreen. Although 71% is a large percentage. Why it could be misleading.
This is very interesting, and I will explain the problems.
a. There is a claim that the product is #1. We need a lot of info in order to substantiate this claim.
Firstly, how many products were compared? Was it #1 amongst 100 products, or were there only 2 in the lineup?
Then, how many dermatologists were asked? If we asked 3 people, it has a lot less validity then if we asked 100 dermatologists to give their opinion.
As well, how was it tested? Was the cream scientifically tested on various attributes, and then was a mathematical model established to see which product tested the highest, and thus was recommended the most?
Was the test done blindly? I.e. - did the researchers show empty bottles, or was the labeling present? Perhaps the dermatologist has preconceived notions of a brand (either positive or negative), which would bias their opinion.
Finally, who did the testing? Was it an independent third ...
The solution discusses an ad for moisturizing lotion specifically adult use of sunscreen.
