Accepted Answer

Judgment samples are often used in exploratory research where the researcher uses their expertise to select subjects that are most useful or representative for the study.

Question 2

Which of the following are valid population elements?

Question 10

In probability samples, the probabilities of each element being included must be

Accepted Answer

In probability samples, the probabilities of each element being included must be known and nonzero to ensure that every element has a chance of being selected and that the selection process is transparent and measurable.

Question 11

One of the major problems with mail surveys is nonresponse bias. In an effort to minimize this, a researcher decides to limit the sample to his personal friends from whom he is sure to get replies. This is an example of a

Accepted Answer

This is an example of a nonprobability sample because the researcher is selecting participants based on personal relationships rather than random selection, which does not allow for generalization to the larger population.

Question 12

Question 15

A researcher wants to interview members of the junior class in a local high school that are interested in attending______________ the local university in order to investigate their attitudes concerning the university's admissions policy. Although the researcher suspects that many of the juniors are interested in attending, the researcher cannot get a list of juniors but only has the names of the three students that have expressed their interest by writing to the admissions office. What sampling procedure should the researcher use to assemble a sample of adequate size?

Accepted Answer

Snowball sampling is appropriate here because the researcher can start with the three known students and ask them to refer other juniors who are interested in attending the university, thus expanding the sample size.

Question 16

Snowball samples are an example of

Accepted Answer

The answer of Snowball samples are an example of
...

Question 17

Which of the following is TRUE?

Accepted Answer

Quota sampling involves selecting respondents based on their similarity to the population in terms of specific characteristics, such as age, gender, and income. This method is often used when it is difficult or expensive to obtain a random sample.

Question 18

Which of the following is a probability sample?

Accepted Answer

A cluster sample is a type of probability sampling where the population is divided into clusters, and a random sample of these clusters is selected for study.

Question 19

All of the following are probability sampling plans EXCEPT

Accepted Answer

Quota sampling is a non-probability sampling method, while area, cluster, simple random, and systematic sampling are all probability sampling methods.

Question 20

A sample where the respondent provides the names of other potential respondents is called a(n)

Accepted Answer

A snowball sample is a non-probability sampling technique where existing study subjects recruit future subjects from among their acquaintances.
