Question 1

Missy is a key informant in Allison's study on teenage girls' study habits. Of the following, which is likely the strategy by which Missy was selected?
A) Random sampling
B) Stratified sampling
C) Criterion sampling
D) Intensity sampling

Accepted Answer

Criterion sampling involves selecting participants who meet specific criteria, such as being a teenage girl with particular study habits, which is likely how Missy was chosen for Allison's study. Random sampling involves selecting participants at random from a larger population, stratified sampling involves dividing the population into strata and then randomly sampling from each stratum, and intensity sampling involves selecting participants who have a particular level of experience or knowledge on a topic. None of these sampling strategies seem to fit the circumstances of how Missy was selected as a key informant.

Question 2

Charleon is conducting a study to examine TechState employees' use of university computers for non-work related tasks. She would like to generalize her findings to all of the employees of the TechState University community.
-If Charleon is conducting this study as a quantitative researcher, which of the following nonrandom sampling strategies might she employ?
A) Snowball sampling
B) Cluster sampling
C) Intensity sampling
D) Quota sampling

Accepted Answer

Quota sampling is a nonrandom sampling strategy that can be used in quantitative research to ensure that specific subgroups are represented in the sample, allowing for generalization to the larger population.

Question 3

Lars is conducting a quantitative study that examines students' achievement within schools, districts, and states in the United States. Which of the following sampling strategies will Lars likely need to use to obtain his sample?
A) Snowball
B) Cluster
C) Criterion
D) Simple random

Accepted Answer

Lars needs to obtain a sample that represents students' achievement across different schools, districts, and states in the United States. Cluster sampling will allow him to randomly select a cluster of schools, districts, or states and gather data from all the students within that cluster. This will help him to ensure that his sample is representative of a larger population. Simple random sampling is a common method used to select individual members within each cluster randomly. Therefore, Lars should use cluster sampling to select schools, districts, and states randomly, and then use simple random sampling to select individual students within each cluster.

Question 4

Of the following, which is a common example of demographic information collected in a survey study?
A) opinion
B) gender
C) interest
D) ability

Accepted Answer

Gender is a common example of demographic information collected in a survey study. Demographic information refers to characteristics of a population such as age, gender, income, education level, and ethnicity. Opinion, interest, and ability are not examples of demographic information, but rather attitudinal or behavioral information.

Question 5

Matt is a qualitative researcher interested in the benefits of community gardens on respect for cultural diversity. He questions whether working together in a gardening environment changes people's tolerance for cultural differences. To conduct his study he selects 8 members of a community gardening group who are Anglo Americans whose families have been in the country for at least three generations and who have been members of the gardening community for at least two years. The sampling strategy Matt is using is best described as ____________ sampling.
A) Homogeneous
B) Criterion
C) Stratified
D) Intensity

Accepted Answer

Matt is using criterion sampling because he selects participants based on specific criteria: being Anglo Americans, having families in the country for at least three generations, and being members of the gardening community for at least two years.

Question 6

Tavares is a quantitative researcher interested in surveying members of a particular school district regarding their opinions on funding for language instruction. He develops a survey to mail to those living in the district. He wants to assure that he has responses from district members across the range of Socio-Economic Status. Of the following, which is the best way for Tavares to assure he has adequate sample size and representativeness?
A) Convenience sampling
B) Systematic sampling
C) Cluster sampling
D) Intensity sampling

Accepted Answer

Cluster sampling is the best option for Tavares because it involves dividing the population into clusters or groups, and then randomly selecting a representative sample from each cluster. This method is more efficient and cost-effective, and ensures that all subgroups of the population are represented in the sample. Convenience sampling (A) may not be representative of the population, systematic sampling (B) may introduce bias if there is a pattern in the selection process, and intensity sampling (D) is not a recognized sampling method.

Question 7

Charleon is conducting a study to examine TechState employees' use of university computers for non-work related tasks. She would like to generalize her findings to all of the employees of the TechState University community.
-Given Charleon's study, which of the following is the target population?
A) Members of University communities in the United States
B) Staff members of TechState University
C) Employees including faculty and staff of TechState University
D) Employees of the Universities in her geographic region

Accepted Answer

The target population for Charleon's study is employees including faculty and staff of TechState University, as she wants to generalize her findings to all employees of the TechState University community. Choices A, B, and D are too broad, as they include populations outside of the specific university community that she is studying.

Question 8

Ina explores eating disorders among male athletes. Nick is a key informant in her study. Which of the following is the most likely sampling strategy that Ina used in her research?
A) Random sampling
B) Stratified sampling
C) Intensity sampling
D) Criterion sampling

Accepted Answer

Intensity sampling is often used in qualitative research to select information-rich cases that manifest the phenomenon intensely but not extremely, making it suitable for studying specific issues like eating disorders among male athletes.

Question 9

Gimbya is completing a narrative study on the benefits of accommodations for post-secondary students at her small liberal arts college. Of the following which is likely her sampling strategy?
A) homogeneous sampling.
B) simple random sampling.
C) cluster sampling.
D) random purposive sampling.

Accepted Answer

Homogeneous sampling is likely her strategy because it involves selecting a specific subgroup that shares similar characteristics, such as being post-secondary students at a small liberal arts college, to explore the benefits of accommodations.

Question 10

Yohance intends to conduct a large survey study that examines access to higher education among urban populations in Mexico. Of the following, which is most likely the sampling strategy that Yohance will consider?
A) Snowball sampling
B) Intensity sampling
C) Stratified sampling
D) Convenience sampling

Accepted Answer

Stratified sampling would be the most appropriate sampling strategy for Yohance's study as it involves dividing the population into subgroups based on certain characteristics such as age, gender, and education level, and then randomly sampling individuals from each subgroup. This would help ensure that the sample is representative of the population and would allow Yohance to make more accurate generalizations about access to higher education among different urban populations in Mexico. Snowball sampling, intensity sampling, and convenience sampling are less suitable for this type of study as they may result in biased or non-representative samples.

Question 11

Which of the following are two general indicators that determine adequacy in sample size?
A) Representativeness and redundancy
B) Generalizability and representativeness
C) Redundancy and clarity
D) Responsiveness and generalizability

Accepted Answer

The answer of Which of the following are two general...

Question 12

A political polling organization has decided to do a study that explores teachers' opinions about school vouchers. To be representative the group seeks data from 1200 practicing teachers in four regions of the United States. The group used an electronic survey and when 1200 surveys are returned, the data are analyzed. This best represents which of the following strategies?
A) Cluster sampling
B) Random sampling
C) Stratified sampling
D) Quota sampling

Accepted Answer

Quota sampling is a non-probability sampling method in which researchers select participants based on specific characteristics, such as age, gender, or ethnicity, to ensure that the sample reflects the proportions of these characteristics in the population. In this case, the polling organization used an electronic survey to collect data from 1200 practicing teachers in four regions of the United States, ensuring that the sample was representative of the population of teachers in terms of region.

Question 13

Which of the following is NOT a purposive sampling technique?
A) Snowball
B) Criterion
C) Intensity
D) Cluster

Accepted Answer

Cluster sampling is a probability sampling technique, not a purposive sampling technique.
