Question 1

When a researcher puts the name of each person on a sampling frame list on a 3" x 5" card,shuffles the cards thoroughly,and then selects 35 names from the top of the pile of cards for a phone interview study,this is an example of what type of sampling procedure?
A) judgment sample
B) simple random sample
C) stratified sample
D) area sample

Accepted Answer

This is a simple random sample because each person on the sampling frame list has an equal chance of being selected, and the selection is done randomly through shuffling the cards.

Question 2

In which type of sampling does every element in the population have a known,nonzero probability of selection?
A) absolute sampling
B) relative sampling
C) nonprobability sampling
D) probability sampling

Accepted Answer

Probability sampling techniques ensure that every element in the population has a known, nonzero probability of being selected, making it the best choice. Absolute sampling and relative sampling are not recognized terms. Nonprobability sampling techniques do not guarantee every element in the population has a chance of being included in the sample.

Question 3

All of the following are advantages of quota sampling over probability sampling EXCEPT ____.
A) lower cost
B) convenience
C) speed of data collection
D) lower error

Accepted Answer

Quota sampling does not guarantee random selection and therefore has a higher sampling error compared to probability sampling methods.

Question 4

When the head of the marketing research department instructs field interviewers to interview parents at a soccer tournament such that they each interview 10 truck owners,10 SUV owners,8 sedan owners,and 4 owners of sports cars,this represents what type of sampling procedure?
A) systematic sample
B) quota sample
C) area sample
D) multistage sample

Accepted Answer

The given scenario represents a quota sample as it involves the interviewers being instructed to meet a specific quota of participants from each category, regardless of the sampling method used to select the participants initially.

Question 5

Which of the following is a nonprobability sampling technique in which an experienced individual selects the sample based on his or her judgment about some appropriate characteristics required of the sample member?
A) area sample
B) subjective sample
C) stratified sample
D) judgment sample

Accepted Answer

Judgment sampling is a nonprobability sampling technique in which an experienced individual selects the sample based on his or her judgment about some appropriate characteristics required of the sample member. Area sampling involves dividing the population into smaller geographic areas and selecting a sample from each area. Stratified sampling involves dividing the population into subgroups and selecting a sample from each subgroup. Subjective sampling is not a recognized sampling technique.

Question 6

As sample size ______ ,random sampling error ______.
A) increases; increases
B) decreases; decreases
C) increases; decreases
D) increase; remains unchanged

Accepted Answer

As sample size increases, random sampling error decreases. This is because a larger sample size reduces the chance of sampling bias and provides a more representative sample of the population.

Question 7

When a marketing vice-president tells the marketing department to schedule a test market in Dallas because he feels that this city is "typical" of the composition of the target market for a new product nationally,this is an example of what type of sample?
A) judgment sample
B) area sample
C) cluster sample
D) convenience sample

Accepted Answer

A judgment sample is when a sample is chosen based on the expertise or judgment of the person selecting the sample. In this case, the marketing vice-president is using his judgment to select Dallas as a representative city for the target market for the new product.

Question 8

When a researcher uses students to participate in a study because he has easy access to them,what type of sampling procedure does this represent?
A) judgment sample
B) systematic sample
C) snowball sample
D) convenience sample

Accepted Answer

This represents a convenience sample, as the researcher is selecting participants based on their easy availability and accessibility, rather than using a random or systematic sampling method. This type of sampling can lead to biased results as the sample may not be representative of the larger population.

Question 9

Which type of sampling procedure selects initial respondents using probability methods and selects subsequent respondents from information provided by those initial respondents?
A) snowball sample
B) stepwise sample
C) judgment sample
D) secondary sampling

Accepted Answer

A snowball sample begins by selecting initial respondents using probability methods (such as random sampling or stratified sampling). However, subsequent respondents are selected based on information provided by those initial respondents, thus creating a "snowball" effect. This approach can be useful when the population of interest is difficult to identify or contact directly, such as with rare or stigmatized populations.

Question 10

Which type of sampling error is primarily due to the nature of a study's design and the correctness of execution?
A) random sampling error
B) systematic sampling error
C) primary sampling error
D) secondary sampling error

Accepted Answer

Systematic sampling error is primarily due to the nature of a study's design and the correctness of execution. It occurs when there is a problem with the way that the sample is selected or when the sample size is too small. Random sampling error, on the other hand, is due to chance and can be reduced by increasing the sample size. Primary and secondary sampling errors are not recognized types of sampling error.

Question 11

When a local television station sends a crew to interview joggers in the city park on a beautiful spring day,this represents what type of sample?
A) cluster sample
B) multistage area sample
C) systematic sample
D) convenience sample

Accepted Answer

A convenience sample is a type of non-probability sampling where the sample is chosen based on the ease of access to participants. In this case, the television station is selecting joggers who are readily available in the city park.

Question 12

Claire has agreed to participate in surveys online.Every few weeks,she is sent an email requesting her to participate in an online survey.What did Claire do to become involved in these research studies?
A) opted out
B) opted in
C) randomized herself
D) met a quota

Accepted Answer

Claire opted in to participate in the online surveys by agreeing to be part of the research study.

Question 13

In which type of sampling is a subsample drawn using simple random sampling within each stratum of the population?
A) cluster sampling
B) stratified sampling
C) systematic sampling
D) convenience sampling

Accepted Answer

In stratified sampling, the population is divided into homogeneous groups or strata and a subsample is drawn using simple random sampling within each stratum. This ensures that the sample is representative of the population in terms of the characteristics of interest, as each stratum is proportionally represented in the final sample. Cluster sampling involves dividing the population into clusters and randomly selecting some of those clusters for inclusion in the sample, while systematic sampling involves selecting every kth element from a list of the population. Convenience sampling involves selecting individuals who are easy to access or who volunteer to participate, and is not considered a representative sampling method.

Question 14

The difference between the sample result and the result of an accurate census is called _____.
A) random sampling error
B) systematic sampling error
C) primary sampling error
D) secondary sampling error

Accepted Answer

The difference between the sample result and the result of an accurate census is called random sampling error as it occurs due to chance variations in the selection of sampling units. Systematic sampling error occurs due to a consistent bias in sample selection, whereas primary and secondary sampling errors are not recognized terms in statistical sampling.

Question 15

A sampling procedure that assures each element in the population of an equal chance of being included in the sample is called _____.
A) simple random sampling
B) primary random sampling
C) primary sampling
D) stratified sampling

Accepted Answer

Simple random sampling ensures that every element in the population has an equal chance of being selected, making it a fair and unbiased sampling method.

Question 16

A stratified sample in which the number of sampling units drawn from each stratum is in proportion to the population size of that stratum is called a(n)_____.
A) proportional stratified sample
B) balanced stratified sample
C) even stratified sample
D) primary stratified sample

Accepted Answer

A proportional stratified sample ensures that the sample is representative of the population by taking into account the proportion of each stratum in the overall population. This method helps to reduce sampling bias and increase the accuracy of the results.

Question 17

If a researcher wants to select 50 customers from a sampling frame of 250 customers who have purchased at least $10,000 worth of products from his company within the past six months using a systematic sampling technique,after a random start,the researcher should select every ______ name on the list.
A) 20th
B) 10th
C) 5th
D) 50th

Accepted Answer

Systematic sampling involves selecting every kth element from a population. In this case, the researcher wants to select 50 customers from a population of 250 customers who have purchased at least $10,000 worth of products within the past six months. Therefore, the sampling interval (k) should be:
k = population size / sample size
k = 250 / 50
k = 5
So, the researcher should select every 5th name on the list after a random start. Therefore, the answer is C) 5th.

Question 18

Internet surveys probably should remain active for a minimum of _____ hours.
A) 5
B) 12
C) 24
D) 48

Accepted Answer

The answer of Internet surveys probably should remain active for...

Question 19

A marketing researcher wants to put together four focus groups of 18-24 year-old males who are "heavy downloaders of music" (defined as downloading 50 songs per month).He finds one person in the target market who qualifies and then asks that person to suggest the names of two other males between the ages of 18-24 who download music so that he can invite them to participate in the focus group.These people,in turn,are each asked to suggest two others similar to themselves to participate in the focus group study.This procedure represents what type of sampling procedure?
A) stepwise sample
B) judgment sample
C) area sample
D) snowball sample

Accepted Answer

This represents a snowball sampling procedure, where initial participants are used to recruit additional participants who fit the criteria.

Question 20

A sampling procedure in which a starting point is selected by a random process and then every nth number on the list is selected is called a(n)_____.
A) cluster sampling
B) analytic sampling
C) systematic sampling
D) stratified sampling

Accepted Answer

The description matches the systematic sampling procedure, where a random starting point is selected and then every nth unit is included in the sample.
