Question 1

Characterize the ideal sampling frame.How often is an "ideal" sampling frame available? If an "ideal" sampling frame isn't available,what kind of sample frame is needed?

Accepted Answer

The answer of Characterize the ideal sampling frame.How often is...

Question 2

A researcher invokes a pilot sample and finds that respondents from households
with less than $50,000 annual income respond very differently than respondents from households with greater than $50,000 annual income,with regard to the key survey questions.In addition,the researcher's preliminary results show greater variance among respondents in the over $50,000 households.Given the preceding,which probability sampling method should the researcher invoke and why?

Accepted Answer

The answer of A researcher invokes a pilot sample and...

Question 3

A researcher is developing a body of knowledge for the development of a formal questionnaire.Part of the process involves conducting four focus groups.Outline an appropriate sampling strategy for generating the focus-group respondents.

Accepted Answer

The answer of A researcher is developing a body of...

Question 4

The key to making accurate predictions about the characteristics or behavior of a large population on the basis of a relatively small sample lies in the way in which individuals are selected for the sample.

Accepted Answer

This statement is true. The sample must be representative of the population in order for accurate predictions to be made. Random and unbiased sampling techniques are typically used to ensure that the sample is representative.

Question 5

When & why does sampling error occur? If the sampling error emanates from some type of improper execution of the sampling plan what is it called? Can it be measured? What kind of sampling error can be measured and how can it be reduced?

Accepted Answer

The answer of When & why does sampling error occur?...

Question 6

The final step in the sampling process is execution of the operational sampling plan.

Accepted Answer

Execution of the operational sampling plan is indeed the final step in the sampling process, after which the data can be collected and analyzed.

Question 7

Developing an appropriate sampling frame is often one of the easiest things that a researcher faces.

Accepted Answer

Developing an appropriate sampling frame can be one of the most challenging aspects of research, as it often requires identifying and accessing a population of interest.

Question 8

Multistage area (probability)sampling is used for national surveys or surveys that cover large regional areas.

Accepted Answer

Multistage area sampling is commonly used for national surveys or surveys that cover large regional areas as it allows for efficient and representative sampling of a large population across various geographic regions.

Question 9

Suppose a marketing researcher was doing a survey of snow skiers residing in South Louisiana,for the specific purpose of estimating the feasibility of offering discounted snow ski rental equipment.The idea was gauge the need,interest and price expectations of these snow skiers as they head to Colorado or some other snow skiing destination.What type of sample would be needed?

Accepted Answer

The answer of Suppose a marketing researcher was doing a...

Question 10

Proportional allocation is also referred to as optimal allocation.

Accepted Answer

Proportional allocation and optimal allocation are different strategies used in sampling. Proportional allocation distributes samples based on the proportion of the population in each stratum, while optimal allocation distributes samples based on minimizing variance for a given sample size, taking into account the variability within each stratum and the cost of sampling.
