Say you were doing a survey to find out how tall people are in your school.
You randomly choose 50 players off the year 12 boys and record their heights.
Would this be a fair, representative, selection of the students.
Of course it would not, it was a bisased survey!

For an unbias survey you might choose a stratified selection.
You might randomly choose 4 girls and 4 boys from each year and record their heights.
That would be an unbiased survey
If the question is "How many black people live in your neighborhood?" Then that is un biased.
If it asks "How many niggers live in the hood?" Then that is biased.
