Studdy Solution

STEP 1

1. The problem involves understanding types of bias in survey sampling.
2. The focus is on the bias caused by individuals choosing to participate on their own.

STEP 2

1. Define the types of bias listed.
2. Identify the correct type of bias for the given scenario.

STEP 3

Define "voluntary response bias":
Voluntary response bias occurs when individuals choose to participate in a survey on their own, often leading to a sample that is not representative of the population because those with strong opinions are more likely to respond.

STEP 4

Define "undercoverage":
Undercoverage occurs when some members of the population are inadequately represented in the sample.

STEP 5

Define "response bias":
Response bias occurs when there are factors that influence the responses of participants, such as the wording of questions or the presence of an interviewer.

STEP 6

Define "non-response bias":
Non-response bias occurs when a significant number of individuals selected for the sample do not respond, and those who do respond differ in meaningful ways from those who do not.

STEP 7

Identify the correct type of bias for the scenario:
The scenario describes a situation where individuals choose on their own whether to participate. This is characteristic of "voluntary response bias."
The form of bias is:
voluntary response \boxed{\text{voluntary response}}
