Hey there,
Your question states: Write a definition of bias and write one biased and one unbiased question to illustrate a definition
The word "bias" means to judge something either before you see it or even when you do see it, and all you do is talk about it and you do not know the information about it. Being bias is an opinion. Not a fact.
One biased question would be: "Where do you like to party."
This would be biased because your basically saying that this person loves to party. How do you even know if he likes to party in the first place. This would be biased.
A question that is not biased: What do you like to do when you have your weekends off.This would not be biased because the person asking the question is not asking a specific question weather the person likes to do things. He's asking if he would do such things, what would he do. Not a straight forward question.
Hope this helps.
