Question 1

Which of the following is the most popular type of cluster sample in marketing research?

Accepted Answer

E

Question 2

In Internet sampling,the interviewing of respondents is essentially volume-insensitive.

Accepted Answer

In Internet sampling, the interviewing of respondents is essentially volume-insensitive, meaning that the number of respondents interviewed does not significantly affect the quality of the sample data collected. This is due to the fact that Internet surveys can reach a larger and more diverse pool of respondents compared to other survey methods, allowing for greater representation of the target population.

Question 3

In a political science study,t he list of registered voters in Webster Groves,Missouri,is
Called the:

Accepted Answer

The list of registered voters in Webster Groves, Missouri is the sampling frame, which is a list of all units (in this case, voters) in a population (in this case, the town), from which a sample is drawn. The other choices are not applicable in this context.

Question 4

What type of sampling procedure is being used if all of the students in all of the sections
Of undergraduate marketing research at Webster University in St.Louis during fall semester are included in the sample of a research study?

Accepted Answer

The sampling procedure described involves selecting all students from a specific group (undergraduate marketing research sections at Webster University), which is a convenience sample as it is based on ease of access rather than random selection.

Question 5

It is not necessary to select a random starting point as the first step in selecting a
systematic sample.

Accepted Answer

Selecting a random starting point is crucial in systematic sampling to ensure that the sample is unbiased and representative of the entire population.

Question 6

If the population has 3,000 people in it and the desired sample size if 600 people,the
Probability of a sample element being selected is about:

Accepted Answer

The probability of a sample element being selected is calculated by dividing the sample size by the population size: 600/3000 = 0.20.

Question 7

Suppose that you wanted to select a stratified random sample of graduate students by
Gender for an in-depth personal interview of 50 students about the curriculum for a Master's degree in Marketing.If the Marketing M.A.program had 200 students enrolled in it,and 60 percent were females and 40 percent were males,how many males would you select from the sampling frame?

Accepted Answer

Since stratified random sampling is being conducted by gender, we need to ensure that our sample proportionately represents the population. 
Out of the 200 students, 60% are females and 40% are males. 
If we need a sample of 50 students, we can calculate the number of males to be selected as follows:

Number of females in population = 0.60 x 200 = 120 
Number of males in population = 0.40 x 200 = 80

Now we can calculate the proportion of males needed in the sample:

Proportion of males in sample = (number of males in population/total population) x sample size 
Proportion of males in sample= (80/200) x 50 = 20

Therefore, we need to select 20 males for our stratified random sample. Answer: D) 20

Question 8

In simple random sampling,the probability of a sample element being selected for the
Sample equals the desired sample size ________ the population size.

Accepted Answer

In simple random sampling, each element of the population has an equal chance of being selected for the sample. Therefore, the probability of an element being selected is the size of the sample divided by the size of the population.

Question 9

The purpose of sampling is to use the results of the sample to estimate some
characteristic of the population from which the sample was drawn.

Accepted Answer

Sampling is used to gather data from a subset of the population in order to make inferences about the population as a whole. The goal is to estimate some characteristic of the population based on the data collected from the sample. Therefore, the statement is true.

Question 10

Which of the following sampling methods is the best known and most widely used
Probability sampling method in marketing research?

Accepted Answer

Simple random sampling is the most widely used probability sampling method in marketing research. It involves selecting a sample from a population in such a way that every unit in the population has an equal chance of being selected. This ensures that the sample is representative of the population and reduces the possibility of bias.

Question 11

The main advantage of snowball sampling is to reduce the search costs for selecting the
sample or potential respondents.

Accepted Answer

Snowball sampling involves asking initial participants to refer other potential participants, which can reduce the time and effort needed to find and recruit participants for a study. Therefore, the statement is true.

Question 12

The first step in developing a sampling plan is to:

Accepted Answer

Defining the population of interest is the starting point for any sampling plan as it determines who or what will be included in the sample. Without this information, it is impossible to move forward with selecting a sampling frame, determining the sample size, choosing a data-collection method, or deciding on an operational procedure for selecting the sample.

Question 13

When a marketing researcher who is performing an exploratory research study has
Researchers ask people in a shopping mall which brand of television they own and why they purchased that brand,and asks the researchers to survey 10 shoppers who own the RCA brand,15 shoppers who own the Toshiba brand,and 12 shoppers who own the Panasonic brand,what type of sampling procedure is being used?

Accepted Answer

The researcher is not selecting the shoppers randomly, but rather using a quota sampling procedure by purposely selecting specific numbers of shoppers who own each brand of television. This allows the researcher to obtain a representative sample of each brand's customers and gather insights into their purchasing behaviors.

Question 14

The difference between the sample value and the population value is called the:

Accepted Answer

The difference between the sample value and the population value is called sampling error, which occurs due to the random nature of selecting a sample from a larger population. The other options (true value, design error, administrative error) do not accurately describe this difference.

Question 15

The list of people from which the researcher plans to select a sample of potential
Respondents is called the:

Accepted Answer

The sampling frame is the list of individuals or units from which a sample is selected. It is important to have a well-defined and representative sampling frame in order to obtain a valid sample that can be generalized to the population of interest. The other options (area sample, convenience sample, population, and sample) are not the appropriate terms for describing the list of potential respondents.

Question 16

In systematic sampling,the skip interval equals the population size ________ the desired
Sample size.

Accepted Answer

In systematic sampling, each member of the population has an equal chance of being selected. To achieve this, the skip interval is calculated by dividing the population size by the desired sample size. Therefore, the correct answer is B, divided by.

Question 17

A sample includes every member of the population of interest to the researcher.

Accepted Answer

A sample is a subset of the population, not the entire population. A census includes every member of the population.

Question 18

When a marketing researcher at Procter & Gamble decides to perform a test market for a
New type of shampoo in St.Louis and Kansas City,what type of sampling procedure is being used?

Accepted Answer

Judgment sampling is used when the researcher selects specific locations or groups based on their knowledge and judgment about which will provide the most useful data. In this case, the researcher chose St. Louis and Kansas City for the test market based on their judgment.

Question 19

The entire group of people about whom the researcher wants to obtain information in a marketing research study is called the:

Accepted Answer

The population is the entire group of people about whom the researcher wants to obtain information in a marketing research study. This group represents the target market or the group of individuals who would be potential customers for the product or service being studied.

Question 20

When a marketing researcher wants to interview teenagers between the ages of 16 -19
About what types of music they prefer,and asks the researchers to go to a shopping mall and ask teenagers if they own at least 100 music CDs in order to select her interview sample,and then asks shoppers who qualify for this screening question to suggest the names of two of their male friends who own at least 100 music CDs to see if they want to participate in the study as well,what type of sampling procedure is being used?

Accepted Answer

This is a snowball sample because the initial respondents are asked to suggest additional respondents who meet the screening criteria. This type of sampling is often used when the target population is difficult to reach or when a researcher wants to study a specific group of people who may have connections to others in that group.
