Question 8

True or False: The professor of a business statistics class wanted to find out the mean amount of time per week her students spent studying for the class.Among the 50 students in her class,20% were freshmen,50% were sophomores and 30% were juniors.She decided to select 2 students randomly from the freshmen,5 randomly from the sophomores and 3 randomly from the juniors.This is an example of a systematic sample.

Accepted Answer

This is not an example of a systematic sample, since the selection process is not based on a predetermined order or interval. Rather, it is an example of stratified random sampling, where the population is divided into subgroups (freshmen, sophomores, and juniors) and a random sample is selected from each subgroup.

Question 9

True or False: To gather opinions on the efficacy of U.S.foreign policies,a sample of 50 faculty members is selected from the pool of university professors who have taught political science at the graduate level.This is an example of a judgment sample.

Accepted Answer

A judgment sample is a non-random sample that is selected based on the judgment of an expert or knowledgeable individual. In this case, the sample of faculty members was selected based on their expertise in political science, making it a judgment sample.

Question 13

True or False: The only way one can eliminate sampling error is to take the whole population as the sample.

Accepted Answer

Sampling error refers to the variability that occurs in the sample that is not representative of the whole population. The only way to ensure that there is no sampling error is to take the entire population as the sample. However, this is not always practical or possible as in most cases, the population is too large. Therefore, researchers use strategies like random sampling, stratified sampling, or cluster sampling to select a representative sample and minimize the sampling error.

Question 14

True or False: An electronic appliance chain gathered customer opinions on their services using the customer feedback forms that are attached to the product registration forms.This is an example of a convenience sample.

Accepted Answer

This is an example of a convenience sample because the sample was taken from customers who conveniently filled out the attached feedback forms, rather than randomly selected from the entire population of customers who purchased from the appliance chain.

Question 15

True or False: Coverage error can become an ethical issue if a particular group is intentionally excluded from the frame.

Accepted Answer

Coverage error involves underrepresenting or leaving out certain groups or aspects in the frame, which can result in biased or inaccurate reporting. Intentional exclusion of a particular group can have negative effects on their representation and social perception, and can therefore become an ethical issue.

Question 16

True or False: The question "How many times have you abused illicit drugs in the last 6 months?" will most likely result in nonresponse error.

Accepted Answer

Asking about illicit drug abuse can be a sensitive and personal topic, and individuals may be hesitant to disclose this information or may feel ashamed. This can lead to nonresponse error, where individuals refuse to answer or provide inaccurate responses.
