What the MCO 03 Solved Question Paper June 2026 covers
MCO 03 Solved Question Paper June 2026 answers all 9 questions of MCO 03 Research Methodology and Statistical Analysis, the third-semester course on business research and statistics in IGNOUβs Master of Commerce (M.Com).
The June 2026 paper, printed with the code MCO-003, carried 9 questions of 20 marks each, and students had to attempt any five in 3 hours. Our subject experts took this official IGNOU paper and wrote a complete answer for every question, in the length and structure examiners look for.
This paper leans heavily on Block 1. Four of its nine questions come from research methods, research design, data collection and sampling, while the rest test time series, index numbers, regression, chi-square, central tendency and five short-note topics.
If you are comparing sessions across courses, our IGNOU Previous Year Question Paper page collects them in one place. For MCO 03, the repeat table further down shows which June 2026 topics were already asked in official papers since June 2023.
MCO 03 sample solved questions from the June 2026 paper
Two questions from the June 2026 MCO 03 Question Paper are solved in full below: Q1 on the methods of research and Q2 on research design and workable hypotheses.
Both are 20-mark questions, and the answers are written the way an examiner expects for that weight. The remaining seven questions follow, word for word as printed in the paper, and their answers are kept only in the full file.
Question 1: Methods of Research
Q1. What are the various methods of research ? Explain them briefly with suitable examples. 20
Answer
Research methods are the procedures a researcher uses to collect, organise and analyse information so that a research question can be answered with evidence rather than opinion. In business research the choice of method depends on the nature of the problem, the kind of data needed, the time and money available and the level of accuracy required. The main methods are explained below.
1. Survey method
The survey method collects information from a group of respondents, usually a sample drawn from a larger population, through a questionnaire, a schedule or personal interviews. It is the most widely used method in commerce research because it covers many people at a reasonable cost and produces data that can be tabulated and tested statistically.
Example: a private bank wants to know why customers are slow to adopt its mobile app. It surveys 500 account holders across age groups on ease of use, trust and network problems, and compares the replies of users and non-users. The limitation is that a survey records what people say, not what they actually do.
2. Observation method
Under the observation method the researcher watches and records behaviour as it actually happens, instead of asking people about it. Observation may be participant or non-participant, structured (with a checklist) or unstructured, and carried out in a natural or a controlled setting.
Example: a supermarket chain records how shoppers move through the store, where they stop and how long they wait at the billing counter, to decide where to place high-margin products. Observation gives first-hand evidence of behaviour, but it cannot reveal motives, and the observerβs judgement may colour the record.
3. Case study method
The case method is an intensive study of a single unit, such as one firm, one department, one event or one person. The unit is studied as a whole and over time, using records, interviews and observation, to understand how and why things happened.
Example: a researcher studies one family-owned textile company to see how control passed from the founder to the next generation and how this affected growth. Case studies give deep insight and help to frame hypotheses, but the findings of one case cannot easily be generalised to all firms.
4. Experimental method
In the experimental method the researcher deliberately changes one factor (the independent variable), holds other factors constant and measures the effect on another factor (the dependent variable). It is the strongest method for establishing cause and effect, and it may be carried out in a laboratory or in the field.
Example: an FMCG company sells the same soap at two different prices in two towns that are similar in income and population, keeps advertising identical in both, and compares the change in sales to judge the effect of price. Full control is hard in real markets, and experiments can be costly.
5. Historical method
The historical method studies past events, records and documents to trace how a phenomenon developed and to explain the present in the light of the past. Its sources include company records, annual reports, government publications and published statistics.
Example: a study of the Indian mutual fund industry from the time the Unit Trust of India began operations in 1964, to show how regulation and investor behaviour shaped its growth. Old records may be incomplete or biased, and they cannot be checked by fresh observation.
6. Comparative method
The comparative method studies two or more units, groups, regions or time periods side by side to find similarities and differences and to identify the factors behind them.
Example: comparing the non-performing assets of public sector and private sector banks over five years to see whether ownership affects credit quality. Comparison sharpens analysis, but the units compared must be genuinely comparable, otherwise the conclusions mislead.
| Method | How data is obtained | Best suited to |
|---|---|---|
| Survey | Questionnaire, schedule or interview of a sample | Opinions and practices of a large group |
| Observation | Watching and recording behaviour as it occurs | Actual conduct of shoppers or workers |
| Case study | In-depth records and interviews on one unit | Understanding how and why within one firm |
| Experimental | Changing one variable and controlling others | Testing cause and effect, such as price on sales |
| Historical | Past documents, reports and statistics | Long-term trends and their causes |
| Comparative | Side-by-side study of two or more units | Finding why groups or periods differ |
Conclusion: in practice a researcher often combines methods. A case study may suggest a hypothesis, a survey may test it on a larger sample and an experiment may confirm the cause. Choosing the right method, or the right mix, is therefore the first step towards reliable business research.
Question 2: Research Design and Workable Hypothesis
Q2. (a) Describe various components of research design. 10
Answer (a)
A research design is the overall plan of a study. It states what is to be studied and why, where and when, from whom data will be collected, how it will be collected and how it will be analysed. A well-drawn design keeps the study focused and saves time and cost. Its main components are as follows.
- Title of the study: short and precise, indicating the subject and scope of the research.
- Introduction or statement of the problem: the background, the issue to be studied and why it matters.
- Review of previous studies: what earlier research has found and the gap this study will fill.
- Scope of the study: the dimensions the study will cover and those it will leave out.
- Objectives: specific, achievable aims that guide data collection and analysis.
- Hypotheses: tentative statements about relationships between variables, to be tested with data.
- Operational definitions: exact meaning of key terms, for example defining a βsmall retailerβ by annual turnover.
- Geographical area: the region, city or market the study will cover.
- Reference period: the time period to which the data will relate.
- Sampling design: the population, sampling unit, sample size and method of selecting the sample.
- Sources and tools of data collection: primary or secondary sources, and tools such as a questionnaire, schedule or interview guide.
- Plan of analysis: how data will be processed and which statistical tools, such as percentages, correlation or chi-square, will be used.
- Significance and limitations: who will benefit from the findings and the constraints of the study.
- Chapter scheme: the tentative chapters in which the final report will be presented.
Example: a study on customer satisfaction with UPI payments among small retailers in Delhi would define a small retailer, fix Delhi as the area and 2025-26 as the reference period, draw a stratified sample of shops, use a structured questionnaire and test its hypotheses with chi-square.
Conclusion: each component answers one practical question about the study. Together they turn a broad idea into a workable plan that another researcher could follow and check.
Q2. (b) Explain criteria for workable hypothesis. 10
Answer (b)
A hypothesis is a tentative statement about the relationship between two or more variables that the researcher sets out to test. Not every guess can serve as a hypothesis. To be workable, that is, usable in actual research, it should meet the following criteria.
- Conceptual clarity: the concepts used must be clearly defined, commonly understood and, where needed, operationally defined, so that everyone reads the hypothesis the same way.
- Specificity: it should state the expected relationship precisely, including its direction, rather than in vague or general terms.
- Empirical testability: it must be capable of verification with observable data. Value judgements such as βadvertising is harmfulβ cannot be tested.
- Related to available techniques: suitable statistical tools and methods of data collection should exist to test it within the time and budget of the study.
- Related to a body of theory: it should grow out of existing knowledge and add to it, not stand in isolation.
- Simplicity: it should explain the relationship with as few variables and assumptions as possible.
- Consistency with known facts: it should not contradict facts that are already well established.
- Stated in a testable form: it should be expressible as a null hypothesis and an alternative hypothesis, so that a decision to accept or reject can be made.
Example: βRetail investors aged below 35 hold a higher share of equity mutual funds in their portfolios than investors aged above 50β is workable: its terms are clear, the direction is stated and it can be tested with survey data. βYoung people are smarter investorsβ is not workable, because βsmarterβ cannot be measured.
Conclusion: a workable hypothesis gives direction to data collection and analysis. If these criteria are ignored, the researcher may collect data that cannot settle the question at all.
Note: the sample answers above were written by our team for this page from the official question text.

MCO 03 question paper pattern and marks split
The MCO 03 Question Paper for June 2026 had 9 questions of 20 marks each, and you answer any five for 100 marks in 3 hours.
| Feature | Marks or count | Where it appears in the paper |
|---|---|---|
| Total questions printed | 9 | Q1 to Q9 |
| Questions to attempt | Any 5 | Choose any five of the nine; the paper has no sections |
| Single 20-mark questions | 20 | Q1 (methods of research), Q8 (central tendency) |
| Parts (a) and (b) | 10 + 10 | Q2, Q4, Q5 and Q7 |
| Two linked tasks in one question | 10 + 10 | Q3: compare questionnaire and schedule, then design a questionnaire |
| Three-way split | 5, 10, 5 | Q6 on regression, its utility and the contrast with correlation |
| Short notes | 5 + 5 + 5 + 5 | Q9: any four of five topics |
| Time and weightage | 3 hours | 100 marks, 70% weightage in the final result |
The 5, 10 and 5 split in Q6 is worth noticing: most students write a long regression answer and then add one line on correlation, losing the last 5 marks. The marks printed beside each part tell you how to divide your writing time.
Students preparing all third-semester courses together can practise the same 20-mark format with our MCOM Question Paper collection.

How our MCO 03 answers are written and checked
Every MCO 03 answer is written by a commerce subject expert and checked by our reviewer against the eGyanKosh units before it goes into the file.
The IGNOU MCO 03 Solved Question Paper is written by Prateek Talwar and reviewed by Sheetal Kirola. Before writing, the team studied earlier MCO 03 papers, so each answer covers the points examiners have rewarded in repeated topics such as research design and chi-square.
Theory answers open with a definition, then explain each point with a business example, and close with a short conclusion. Statistical answers state the formula, define each symbol and explain the result in plain words, because the paper asks you to explain and discuss, not only to compute.

Programmes that include MCO 03 Research Methodology and Statistical Analysis
MCO 03 Research Methodology and Statistical Analysis is a 6-credit core course in the third semester of IGNOUβs M.Com and is shared by its related commerce programmes.
It sits in the third semester of the Master of Commerce (M.Com), after the first-year courses on management, accounting and quantitative analysis. The same course is studied in these programmes:
- MCOM: Master of Commerce (M.Com)
- MCOMOL: M.Com (Online)
- MCOMFT: Master of Commerce in Finance & Taxation
- MCOMBPCG: Master of Commerce in Business Policy and Corporate Governance
- MCOMMAFS: Master of Commerce in Management Accounting & Financial Strategies
Because the course is common, research design and hypothesis questions also help later with the project and dissertation work in these programmes.

MCO 03 Research Methodology FAQs
These answers cover what students most often ask us about the MCO 03 June 2026 solved paper.
Is the MCO 03 Solved Question Paper based on the official June 2026 paper?
Yes. Our experts used the official IGNOU June 2026 Term-End paper for MCO 03, which is printed with the code MCO-003, and answered all 9 questions exactly as they appear. Nothing is a guessed or predicted question. The answers follow the marks split printed against each question, such as 10+10 for Q3 and 5, 10 and 5 for Q6, so you know how much to write for each part.
How do I get the full MCO 03 file with all 9 answers on WhatsApp?
Send a WhatsApp message to 9899436384 saying βMCO 03 June 2026 solved paperβ. Our team replies with the price and payment details, and once payment is confirmed the complete PDF is shared on the same chat. It contains answers to all 9 questions, including the 7 questions not shown on this page and all five short notes asked in Q9 of the paper.
Why does the June 2026 MCO 03 paper show the code MCO-003?
IGNOU printed the June 2026 paper as MCO-003, while the December 2024, June 2025 and December 2025 papers were printed as MCO-03. The course title, the 100-mark pattern and the topics are the same, so students who see either code can prepare from the same answers. Write whichever code appears on your hall ticket when you fill in the answer book.
Which MCO 03 topics repeat most often in IGNOU papers?
Across the six official papers from June 2023 to December 2025, research design was asked in 5 sessions. Hypothesis, primary data collection, time series, chi-square and probability distribution each came up in 4 sessions. Methods of research appeared in December 2024, June 2025 and December 2025, and then again as Q1 in June 2026, so it deserves thorough preparation.
How many questions must I attempt in the MCO 03 exam?
You must attempt any five of the nine questions in the MCO 03 June 2026 paper. Every question carries 20 marks, so the paper totals 100 marks in 3 hours, and the term-end exam carries 70 per cent weightage in your final result. Some questions are split into two 10-mark parts, and Q9 asks for any four short notes out of five.
Is the MCO 03 file useful for M.Com Online and the M.Com specialisations?
Yes. MCO 03 Research Methodology and Statistical Analysis is common to the IGNOU M.Com and its related programmes, including M.Com Online (MCOMOL), Finance and Taxation (MCOMFT), Business Policy and Corporate Governance (MCOMBPCG) and Management Accounting and Financial Strategies (MCOMMAFS). Students of these programmes write the same course, so the June 2026 answers suit all of them.
Which MCO 03 questions are answered on this page?
Q1 on the methods of research and both parts of Q2, the components of research design and the criteria for a workable hypothesis, are answered in full on this page. The other seven questions, Q3 to Q9, are listed only as question text. Their answers, covering data collection, time series, sampling, regression, chi-square, central tendency and the short notes, are in the full file.
Will the MCO 03 June 2026 answers help for the December 2026 exam?
They should help a great deal, because MCO 03 repeats its core themes often. Research design, methods of research, chi-square and time series have each been asked several times since June 2023. IGNOU does not repeat a paper word for word, so use the file to master these themes and revise each answer alongside its unit in the eGyanKosh study material.
