Question 9

Describe the 5 types of error that could impact our class survey and describe one way to
reduce each type of error.

Answer 9

1. Sampling error: comes from collecting info from part
   of the population (difference from sample & pop).
2. Coverage error: when there is missing data on the list (when every unit in the population does not have a known nonzero chance of being in the sample).
3. Non-response error: Occurs when those who do not respond are different from those who do respond.
4. Measurement error: Occurs when questions are misunderstood or incorrectly answered.
5. Interviewer Effect error: When the interviewers create bias in how respondents answer questions.
