Given information:The city council is trying to determine if the city’s residents support the building of a new parking garage. They poll 200 people at the local bus station.
Explanation:
A bias is a systematic error introduced by the sampling method.
The city council is trying to determine if the city’s residents support the building of a new parking garage by polling 200 people at the local bus station.
There is bias because at a bus station, there may be people that do not drive a car and hence have no opinion regarding parking garage as it doesn’t affect them.
