Question 1

PERT is a network approach that divides the marketing research project into multiple components and estimates the time required for each activity.

Accepted Answer

PERT (Program Evaluation and Review Technique) is a project management tool used to plan, schedule, and control complex projects, not specifically for dividing marketing research projects. It focuses on the tasks involved in completing a project, estimating the minimum time needed to complete the whole project by analyzing the time required for each task.

Question 2

The time involved in doing a research study should be considered when calculating the cost of research.An opportunity may be missed if research delays a management decision.

Accepted Answer

Research can be time-consuming, and delays in decision-making can lead to missed opportunities, therefore time should be considered when calculating the cost of research.

Question 3

Constraints, budgeting and scheduling activities ensure that the resources are used effectively and efficiently.

Accepted Answer

The answer of Constraints, budgeting and scheduling activities ensure that...

Question 4

One useful method to anticipate the results of analysis is to produce dummy or fictional data for survey questions and then to analyze that data.

Accepted Answer

This method is known as "testing on simulated data" or "simulation testing" and is commonly used in data analysis to test the reliability and validity of statistical models and methods. By creating fictional data that resembles real data, researchers can test the accuracy and limitations of their analysis techniques in a controlled environment before applying them to real-world data.

Question 5

Sampling frame error occurs when an inappropriate population is chosen for the research study.

Accepted Answer

The answer of Sampling frame error occurs when an inappropriate...

Question 6

One of the research tactics is to translate the research objectives into questions that can be answered by the respondents and then into information requirements.

Accepted Answer

The answer of One of the research tactics is to...

Question 7

Error caused by the improper design of an experiment is measurement error.

Accepted Answer

Measurement error is caused by inaccurate or imprecise measurement techniques, not by the design of the experiment. Experiment design errors can include issues such as selection bias, randomization issues, or confounding variables.

Question 8

Surrogate information error is the difference or variation between the information required for a marketing research study and the information being sought by a researcher.

Accepted Answer

Surrogate information error occurs when there is a discrepancy between the actual information needed for a research study and the information being collected by a researcher. This can lead to inaccurate findings and conclusions.

Question 9

Design errors are also called research induced errors.

Accepted Answer

Design errors are errors that occur during the design phase of a research project. Research-induced errors are errors that are caused by the researcher's own actions or decisions. Therefore, design errors can be considered a type of research-induced error.

Question 10

The total error in a research study is the difference between the true mean value of the variable being studied and the observed mean value obtained through the research study.

Accepted Answer

The total error in a research study is indeed the difference between the true mean value and the observed mean value, encompassing all sources of error such as sampling error, measurement error, and other biases.

Question 11

Selection error occurs when a sample selected is not representative of the population.

Accepted Answer

This is because selection error occurs when the sample selected does not accurately reflect the characteristics of the population from which it was drawn. This can lead to inaccurate results and conclusions.

Question 12

A major challenge that is faced by the researcher in designing the sampling plan is how to minimize nonresponse.

Accepted Answer

Nonresponse can introduce bias into the study and reduce the representativeness of the sample. Therefore, researchers aim to minimize nonresponse by using various techniques such as follow-up calls, offering incentives, and simplifying survey questions.

Question 13

GANTT charts are activity flowcharts that schematically represent the activity, time, and personnel requirements of a research project.

Accepted Answer

GANTT charts are indeed activity flowcharts that show the timeline and personnel requirements for a research project.

Question 14

Although research approaches can be classified into one of three general categories of research, there is no significant difference between the categories.

Accepted Answer

The three general categories of research are qualitative, quantitative, and mixed methods. Each approach has different techniques, data collection methods, and analysis strategies, which can result in unique findings and insights. Therefore, there are significant differences between the categories.

Question 15

Deciding on the sampling plan and anticipating the results of analysis are significant steps in the research process, but at this point it is still too early in the process to allow for a more reliable estimate of the cost of a study.

Accepted Answer

Deciding on the sampling plan and anticipating the results are steps that significantly contribute to forming a more reliable estimate of the cost of a study, as they define the scope and scale of the research, which are critical for budgeting.

Question 16

Response errors occur when the respondent provides inaccurate answers to the research questions.

Accepted Answer

Response errors can occur due to various reasons like memory bias, social desirability bias, and lack of understanding of the questions.

Question 17

When a detailed cost-benefit analysis is done, one decision alternative is to terminate the research study.

Accepted Answer

If a detailed cost-benefit analysis shows that the costs of continuing the research study outweigh the potential benefits, then the decision alternative to terminate the study may be the most rational and efficient choice.

Question 18

The absence of structure in an exploratory research permits a thorough pursuit of interesting ideas and clues about the problem situation

Accepted Answer

Exploratory research is designed to discover insights and ideas about a problem situation. The lack of structure allows for a more open and flexible approach to gathering information and pursuing interesting leads without being constrained by predefined assumptions or theories. This allows for a more thorough exploration of the problem space and can lead to new and unexpected findings.

Question 19

Graphical evaluation and review techniques are essentially a first-generation PERT approach to scheduling, in which both the completion probabilities and activity costs to be built into a network representation are considered.

Accepted Answer

Graphical Evaluation and Review Technique (GERT) allows for probabilistic treatment of both network logic and activity duration estimates, which is more advanced than the first-generation Program Evaluation and Review Technique (PERT) that primarily focuses on deterministic models and does not incorporate activity costs directly into the network model.

Question 20

Because the results of research studies are unpredictable, it is not possible to judge beforehand whether specific cross-tabulations of one question by another will be relevant to the research question.

Accepted Answer

The answer of Because the results of research studies are...
