To find out whether the students really like the school's lunch, the school randomly selects half of the student body to survey about the school's lunch. is this sample of students likely to be biased or unbiased? biased unbiased

The answer would be Biased.

The reason why is because under the circumstances these students would be influenced to say that the food taste's good because there are teachers around them and they feel as if they don't want to get in trouble.

A biased question is when the person asking the question influences the person to answer in a way they like.

A unbiased question is when the question doesn't make affect the readers Decision in any way.
 Hope this helps <3
