Question

Which of these is an example of pseudoscience A scientist wants to find the percent of teens that like the taste of brand X Lemonade over brand Y lemonade. She conducts a taste test of 500 teenagers she gives each team a bottle of lemonade with the label showing the brand of each lemonade. She asks each teenager to taste each brand after drinking water in between.She finds that 50% of teens like brand X and 50% like brand Y Lemonade. Why are the results of the survey most likely unreliable

Answer 1

Answer:

It is not a reliable test because the people's answer may be biased by prior familiarity with the brands they are testing.

Explanation:

The results are most likely unreliable because if the people who are testing the two brands of lemonades (brand X and Y) know the two brands already from before the test, their responses may be biased according to what they believe a priori that is better. In other words, they could simply choose their favorite brand without objectively analyzing the taste.
