Question

A lab is conducting a test to see if people prefer chocolate A or chocolate B. The steps in the test are outlined below: Step 1. Recruit one hundred volunteers and tell them the purpose of the study. Step 2. Give them chocolate A and ask them to rate the flavor. Step 3. Give them chocolate B and ask them to tell how delicious it is. Step 4. Reveal which chocolate they preferred. Which step could lead to biased results?

Answer 1

Step 3

Explanation:

By asking the participants how delicious chocolate B is, you can possibly create bias in the test. It is a leading question; these should not be asked to avoid creating bias.

Answer 2

I'd say step 3 because it's asking how "delicious" it was while step 2 said "rate the flavor." People could give it a 1 in delicious and a 5 in flavor. This leads to unfair results. *Also add about them having a constant and variable.*

Hope that helped! <3
