Question 1

Refer to the following paragraph to answer the questions below.
Robert Warner, president of a local TV station, recently conducted a study of TV viewers in his area. He obtained a list of all residential customers from the cable TV company billing list. Oddly enough, he put every customer name on a 3x5 note card, and mixed them up in one raffle barrel. He then choose 1000 note cards out of a possible 20,000 customer cards). A trained interviewer visited each household and asked detailed questions about the viewing habits of various family members.
-How large is his sampling ratio?
A) 1/200
B) 1/20
C) 1/10

A) population, sample
B) sampling frame, sampling ratio
C) random sample, nonrandom sample
D) parameter, statistic

Accepted Answer

The population is the large group of cases that the researcher wants their study to generalize to, and the sample is the small group of cases that the researcher actually studies.

Question 3

Refer to the following paragraph to answer the questions below.
The Young Children's Charity would like to provide an accurate estimate of how much it costs to raise a child between the ages of 2 and 12 for its fund raising campaign. They contracted with you to find out how much households spent on raising a child in 1996. They gave you a list all 400,000 residential telephone customers in the area they will operate the campaign. You sampled every 400th address on the list. The Charity will have a survey company contact each household sampled and ask whether or not there is a child between 2 and 12 years of age living in the household. If there is, they will ask other questions and record the total amount spent raising a child during 1996.
-What type of sample will you be using?
A) simple random sample
B) stratified random sample
C) systematic random sample
D) convenient sample

Accepted Answer

This is a systematic random sample because every 400th address from the list is selected, following a fixed interval system.

Question 4

A researcher asks students in an introductory sociology class to take an Internet survey on student attitudes towards puppy dogs. What kind of sample is the researcher using?
A) snowball sample
B) purposive sample
C) haphazard sample
D) quota sampling

The researcher is using a haphazard sample because they are asking a readily available group (students in an introductory sociology class) to participate without using a systematic method for selecting participants.

Question 5

What type of sampling did Professor Howlick use?
A) simple random sample
B) cluster sample
C) stratified random sample
D) sequential sample

Accepted Answer

Simple random sampling involves selecting participants from a larger population in such a way that each individual has an equal chance of being chosen. This method is often used to ensure that the sample is representative of the larger group.

Question 14

Vince wants to draw a sample of people in Illinois who own 1960s Schwinn Sting-Ray children's bicycles, a collector's item. There is no list of the people, but there is an informal network acquaintances) of Sting-Ray owners. What type of sampling should Vince use?
A) cluster sampling
B) simple random sampling
C) purposive sampling
D) snowball sampling

Accepted Answer

Snowball sampling is the best method for Vince to use because it leverages the existing network of Sting-Ray owners to identify and recruit other owners, which is particularly useful when there is no formal list of the population of interest.

Question 15

Refer to the following paragraph to answer the questions below.
Dr. Martinez draws a systematic random sample of 350 churches from all churches and religious institutions in the 3 Pacific coast states of the continental U.S. His sampling frame has 35,000 institutions.

The sampling interval is calculated by dividing the total number of institutions in the sampling frame (35,000) by the number of institutions sampled (350), which equals 100.

Question 16

Professor Howlick's questionnaire asked each student to name every other student with whom they had drank with during the past two months. Kerry Sobiski, his assistant, sent emails for the online survey to each person named by students in the first sample. The same question was asked in this online survey. Ms. Sobiski next sent emails for the online survey to everyone named as a drinking partner in the second sample and so on until she had emailed ten different waves of online surveys. She then drew up a list of all students who drank with anyone else who answered the online survey, and used it as a sample for a study on drinking networks on campus. What kind of sampling was Ms. Sobiski using?
A) snowball sampling
B) quota sampling
C) accidental sampling
D) cluster sampling

Accepted Answer

Snowball sampling involves starting with a small group of initial respondents and then expanding the sample by asking those respondents to identify others who fit the study's criteria, which is exactly what was done in this scenario.

Question 17

Professor Hangnail wants to study how people join a small extremist political organization dedicated to right- wing ideas.
