QCM : Fundamentals of Business Research Methods — 12 questions

Questions et réponses du QCM

1. What best describes business research?

A process of selecting respondents based on convenience alone
A casual review of opinions to support personal judgment
A purely theoretical exercise that avoids using data
A systematic process of gathering, recording, and analyzing data to guide managerial decisions

A systematic process of gathering, recording, and analyzing data to guide managerial decisions

Explication

Business research is defined as a systematic, data-based process used to guide managerial decisions. The other options miss the emphasis on structured evidence and decision support.

2. Which type of research is most appropriate when a problem is vague and new ideas are needed first?

Confirmatory research
Causal research
Exploratory research
Descriptive research

Exploratory research

Explication

Exploratory research is used for ambiguous problems and aims to generate insights through flexible, often qualitative, approaches. Descriptive research summarizes what is happening, while causal research tests cause-effect relationships.

3. What is the main purpose of a research design?

To replace the need for hypothesis development
To serve as a blueprint for data collection, measurement, and analysis
To guarantee that every sample member is interviewed in person
To summarize final findings for executives

To serve as a blueprint for data collection, measurement, and analysis

Explication

A research design is the plan that specifies how data will be collected, measured, and analyzed. It acts as a blueprint rather than a results summary or a substitute for hypotheses.

4. What distinguishes probability sampling from non-probability sampling?

Non-probability sampling is used only in experiments
Probability sampling gives each element a known, non-zero chance of selection
Non-probability sampling ensures equal chance for every element
Probability sampling relies mainly on the researcher's judgment

Probability sampling gives each element a known, non-zero chance of selection

Explication

In probability sampling, every population element has a known, non-zero chance of selection. Non-probability sampling depends on judgment rather than a known random mechanism.

5. What does a null hypothesis state?

The measurement instrument is perfectly reliable
The sample is too small for any conclusion
A significant effect or relationship definitely exists
There is no statistically significant difference, effect, or relationship

There is no statistically significant difference, effect, or relationship

Explication

The null hypothesis represents no statistically significant difference, effect, or relationship. The alternative hypothesis is the one that claims a meaningful effect or difference.

6. Which measurement scale provides categories only, with no meaningful order or distance?

Interval scale
Ordinal scale
Ratio scale
Nominal scale

Nominal scale

Explication

Nominal scales classify data into categories without ranking or distance between values. Ordinal data can be ranked, while interval and ratio scales add equal spacing.

7. What does the correlation coefficient measure?

The reliability of a questionnaire over time
The proportion of respondents in each category
The strength and direction of a linear relationship between two variables
The difference between more than two group means

The strength and direction of a linear relationship between two variables

Explication

The correlation coefficient shows both the strength and direction of a linear relationship between two variables. It does not compare group means or measure reliability.

8. Which software is best described as supporting advanced modeling and visualization?

R
A spreadsheet macro only
MS Excel
A word processor

R

Explication

R is described as supporting advanced modeling and visualization. Excel is more associated with basic tabulation, descriptive statistics, and business charts.

9. What is the main purpose of a managerial report?

To minimize jargon and focus on actionable conclusions for executives
To list all raw data without interpretation
To avoid recommendations and leave decisions to readers
To present highly technical methodology for academic peers

To minimize jargon and focus on actionable conclusions for executives

Explication

A managerial report is designed for executives, so it uses less jargon and emphasizes practical conclusions. A technical report, by contrast, focuses more on detailed method and rigor.

10. Which practice is part of ethical reporting?

Using emotional language to persuade the reader
Presenting data honestly without fabrication or distortion
Changing trends that do not match the expected conclusion
Omitting citations to make the report appear original

Presenting data honestly without fabrication or distortion

Explication

Ethical reporting requires honesty, including no fabrication and no distortion of results. The other options are forms of poor or unethical reporting, including plagiarism and bias.

11. What is a key use of natural language processing in research and business analysis?

Comparing means across more than two independent groups
Randomly selecting survey respondents from a population list
Measuring the consistency of a questionnaire across repeated use
Analyzing large volumes of text to identify themes such as sentiment or key topics

Analyzing large volumes of text to identify themes such as sentiment or key topics

Explication

Natural language processing is used to process large text datasets and extract themes like sentiment or topics. The other options describe sampling, ANOVA, and reliability, which are different concepts.

12. Which agency is described as India’s premier policy think tank that produces research-backed frameworks for regional development?

MS Excel
SPSS
NSSO
NITI Aayog

NITI Aayog

Explication

NITI Aayog is identified as India’s premier policy think tank focused on research-backed frameworks for development. NSSO is the agency that conducts large-scale socio-economic surveys, not the policy think tank.
