Does the sampling method have any bias? Explain.
b. The sampling method is self-selected sampling. This method allows individuals to choose whether or not they want to participate in the survey.
Bias may exist in this sampling method because individuals who choose to participate may not be representative of the entire community. Those who are avid readers or have strong opinions about reading habits are more likely to participate, while others may choose not to participate. As a result, the sample may not accurately reflect the community's overall reading habits.
