Question 1

There are at least two general reasons why a sample is almost always more desirable than a census,which include the expense and the difficulty of analyzing very large datasets.

Accepted Answer

Conducting a census can be extremely expensive and time-consuming, and analyzing the data from a census can be very difficult due to the large volume of information collected. A sample is often more manageable and cost-effective.

Question 2

The ________ is a definite sequence of steps which the researcher goes through to draw and ultimately arrive at the final sample.
A)sample plan
B)sample method
C)sample technique
D)sample objective

Accepted Answer

The sample plan is the correct term because it refers to the detailed strategy or roadmap that a researcher follows to identify, select, and ultimately arrive at the final sample for their study. This plan includes the steps and criteria used for selection.

Question 3

Probability samples are samples in which members of the population have a known chance of being selected into the sample.

Accepted Answer

Probability samples are selected randomly, where each member in the population has a known and equal probability of being chosen for the sample. Examples of probability sampling techniques include simple random sampling, stratified sampling, and cluster sampling.

Question 4

Sampling error is caused by two factors,which include the sample definition and the sampling technique.

Accepted Answer

Sampling error is primarily caused by the fact that a sample is only a subset of the population, leading to potential differences between the sample and the population. Sample definition and sampling technique can influence sampling error, but they are not the only causes.

Question 5

A sample frame invariably contains sample frame error,which is the degree to which the sample frame fails to account for all of the population.

Accepted Answer

Sample frame error refers to the errors that occur when the researcher uses an incomplete or inaccurate sampling frame from which to draw the sample. Therefore, a sample frame will inevitably contain sample frame error.

Question 6

A sample frame is not a master source of sample units in the population.

Accepted Answer

A sample frame is indeed a master source of sample units in the population, as it lists or identifies all the elements from which the sample is drawn.

Question 7

Panel companies are especially adept at ________ because they have huge databases of information regarding demographics,possessions,lifestyle,medical ailments,and so on that can be used to select panel members to be survey respondents.
A)conducting large surveys
B)delivering targeted samples
C)reaching social media enthusiasts
D)executing complex surveys

Accepted Answer

Panel companies are able to deliver targeted samples because they have access to a vast amount of information about their panel members, allowing them to select individuals who match the criteria needed for a particular survey. This allows for greater accuracy and specificity in data collection.

Question 8

A sample unit is a subset of the population that suitably represents that entire group.

Accepted Answer

The answer of A sample unit is a subset of...

Question 9

Managers tend to have a less specific definition of the population than do researchers because the researcher must use the description of the population precisely,whereas the manager uses it in a more general way.

Accepted Answer

Researchers need to have a precise understanding of the population they are studying in order to conduct accurate research. Managers, on the other hand, may use a more general definition of the population when making decisions or setting goals.

Question 10

The use of banners,pop-ups,or other online devices that invite website visitors to take part in the survey are indicative of what type of sampling method?
A)Blue ocean samples
B)Online panels
C)River samples
D)List samples

Accepted Answer

River sampling involves intercepting users as they navigate the internet, often through methods like banners or pop-ups, inviting them to participate in surveys. This approach aims to capture a wide and varied audience as they "flow" through the web, similar to a river.

Question 11

Inspecting some relevant characteristics of the sample(such as distribution of males and females,age ranges,etc.)to judge how well it matches the known distribution of these characteristics in the population is known as:
A)Obtaining the sample frame.
B)Defining the sample population.
C)Validating the sample.
D)Drawing the sample.

Accepted Answer

Validating the sample involves checking if the sample characteristics match with the known distribution of the population. This is important to ensure that the sample is representative of the population and the data collected can be generalized to the population. Option A is incorrect as obtaining the sample frame refers to creating a list of eligible individuals or units from which the sample will be selected. Option B is incorrect as defining the sample population refers to identifying the group of individuals or units that the sample will represent. Option D is incorrect as drawing the sample refers to the process of selecting individuals or units from the sample frame to be included in the study.

Question 12

It is not possible to obtain precision or accuracy with surprisingly small samples.

Accepted Answer

Even with small samples, it is possible to achieve precision or accuracy if the sampling method is well-designed and the sample is representative of the population.

Question 13

Whenever a sample is taken,the survey will reflect sampling error.

Accepted Answer

Sampling error refers to the discrepancy between the characteristics of a sample and the characteristics of the population from which it is drawn. It is expected in any random sampling process and can be reduced by increasing the sample size.

Question 14

Nonprobability samples are samples where the chances(probability)of selecting members from the population into the sample are known.

Accepted Answer

Nonprobability samples are samples where the chances(probability) of selecting members from the population into the sample are not known or cannot be calculated.

Question 15

________ are those purchased or otherwise procured from someone or some company that has compiled email addresses of opt-in members of the population of interest.
A)Blue ocean samples
B)Online panels
C)River samples
D)List samples

Accepted Answer

List samples are those purchased or procured from a company that has already compiled email addresses of people who have opted-in to receive emails. This approach can be effective in reaching a specific population of interest; however, it can also be costly and may not always result in high-quality leads.

Question 16

The difficulties encountered by U.S.census takers are identical to those encountered in marketing research.

Accepted Answer

Both U.S. census takers and marketing researchers face challenges related to collecting accurate and complete data from a diverse population. Both also rely on various methods, such as surveys and interviews, to gather information from respondents.

Question 17

A sample is the basic level of investigation.

Accepted Answer

A sample is a subset of a population used for investigation, not the basic level itself. The basic level of investigation would involve defining the problem, formulating a hypothesis, and then possibly using a sample to conduct research or experiments.

Question 18

There are no impracticalities associated with a census,particularly when you think about target markets encompassing millions of consumers.

Accepted Answer

Conducting a census can be a time-consuming and costly process, which may not always lead to accurate data collection. Additionally, some people may choose not to participate in the census, resulting in incomplete or biased data. Therefore, there may be some impracticalities associated with a census.

Question 19

Of the following,which is NOT a step in creating a sample plan:
A)Define the population.
B)Establish the research objective.
C)Decide on the sample method.
D)Draw the sample.

Accepted Answer

Establishing the research objective is a preliminary step in the research process, not specifically a step in creating a sample plan. The sample plan focuses on defining the population, deciding on the sample method, and drawing the sample.

Question 20

The sample and sample unit exist within the area called the sample frame.

Accepted Answer

A sample is a subset of the population, and the sample unit is a single element or individual within that subset. The sample frame includes all potential units or elements from which the sample will be selected. Therefore, the statement that the sample and sample unit exist within the sample frame is correct.
