________ sampling is a probability sampling procedure in which every sampling unit has a known and equal chance of being selected.

Which of the following is a probability sampling method?

• cluster sampling

• snowball sampling

• quota sampling

• judgment sampling

Which of the following is true of simple random sampling?

• It produces unbiased estimates of a target population's characteristics.

• It eliminates the need to identify all sampling units.

• Compared with systematic random sampling, it is less costly because it can be done relatively quickly.

• It requires that a defined target population be ordered in some way, usually in the form of a customer list, taxpayer roll, or membership roster.

Before polling the students of the Scion School of Business, a researcher divides all the current students into groups based on their class standing, such as freshmen, sophomores, and so on. Then, she randomly draws a sample of 50 students from each of these groups to create a representative sample of the entire student body in the school. Which of the following sampling methods is the researcher practicing?

• systematic random sampling

• stratified random sampling

• referral sampling

• snowball sampling

Which of the following is true of convenience sampling?

• It is a nonprobability sampling method.

• It is a time-consuming process if there is a large number of respondents.

• It allows researchers to measure the representativeness of a sample.

• It allows researchers to generalize the data collected to a defined target population.

A college professor wants to know if university students in the United States will find the new textbook that they have authored to be interesting and useful. The professor chooses marketing majors at the school they teach as their sample. The professor believes that this group of students will be representative of the university student population in the United States. In this scenario, the professor is most likely using

• census sampling.

• area sampling.

• judgment sampling

• cluster sampling.

Sarah, a researcher, does not have the resources or time to use a probability sampling method. However, she wants to make sure that all ethnicities are fairly represented in her sample. In this scenario, Sarah is most likely to use ________.

Which method of sampling relies on the assumption that rare groups of people tend to form their own unique social and similar circles?

• judgment sampling

• cluster sampling

• snowball sampling

• convenience sampling

__________ is the blueprint or framework needed to ensure that the data collected are representative of the defined target population.
