STEP 1
What is this asking? Is Danny's survey about favorite sports a good survey, or is it biased because he only asked the football team? Watch out! A biased sample doesn't give everyone an equal chance of being chosen!
STEP 2
1. Understand Bias
2. Analyze Danny's Survey
STEP 3
A **biased** sample means some people are more likely to be picked than others.
It's like only asking your best friends what the best candy is – you'll probably get a biased answer!
A **good sample** gives everyone an equal chance of being chosen.
STEP 4
Danny only asked the football team about their favorite sport.
Does this give everyone in the school an equal chance of being asked?
Nope! Football players are much more likely to be in Danny's survey than anyone else.
STEP 5
Since football players are more likely to be picked, Danny's sample is **biased**.
And because it's biased, the people in the population do **not** have an equal chance of being selected.
STEP 6
Danny's sample is **biased** (A), and everyone in the population does **not** have (B) an equal chance of being selected for the sample.
