Exam 4: Research Design and Implementation

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.

A causal approach should be used when 1-there exists a knowledge of the research problem, the decision alternatives, and the relevant variables. 2-only speculative hypotheses exist. 3-the research methods can be highly flexible. 4-the researcher must show that one variable determines the values of another variable.

To" anticipate the analysis of data" means that a researcher should

Asking experts their opinions and doing depth and focus-group interviews are examples of qualitative research.

After the research objective has been translated into information requirements and then specific questions, data collection is ready to begin.

The research proposal may

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.

Of the following research questions, which could not be answered by exploratory research? 1-How does revenue vary with the size of our company's sales staff? 2-What do customers expect from our product? 3-What are the alternative means of transportation for urban commuters? 4-Are customers satisfied with our product?

Which research approaches) is/are more often guided by an initial hypothesis?

____________ occurs when an inappropriate population is chosen to obtain data for the research study.

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

Because different research methods serve different purposes, a researcher can get into difficulty by combining several methods in a single research study.For that reason, it is best to stick with one method.

The difference between laboratory and field experiments is whether variables are manipulated in an artificial or a natural setting.

If an interviewer fabricates the responses to a survey, it induces an) __________ error.

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

The three research approaches - exploratory, descriptive, and causal--are often used to complement each other in a research study.

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

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

Descriptive research is routinely used to discover all of the following except

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