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

"The lemonade labels introduced bias."

Step-by-step explanation:

By providing the labels showing the brand of each lemonade to the teenagers during the taste test, the scientist introduced a potential bias into the experiment. The knowledge of the brand may have influenced the teenagers' preferences, leading to an equal distribution of preferences between the two brands (50% for each). This bias could undermine the validity of the results because it doesn't solely reflect the intrinsic taste preferences of the lemonades but rather how branding and labeling may have affected the teenagers' choices. To obtain more reliable results, the taste test should have been conducted in a blind or double-blind manner, where the brand information is concealed from the participants.

Answer 2

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

Step-by-step 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.
