Some sources of bias may be:
- The fact the company is calling in such a narrow time window. They need to expand their hours of operation.
- Not everyone has a listed phone number, and many cell phones are unlisted, so that leaves many people out of the picture. The sample is likely not representative of the population. The company may be better off doing email or social media surveying methods.
