Steps of a Statistical Project in Economics

Updated 17 October 2026 · Fact-checked

A statistical project follows steps: identify the problem and objectives, choose the target group and sample, collect data with a tested questionnaire, organise and present the data, analyse and interpret it with suitable tools, and write conclusions, suggestions and a bibliography. Each step should be justified and recorded.

Follow the six steps in order, and justify and record the choices you make at every step.

Understand Steps of a Statistical Project

Purpose. A project applies the statistical tools of the course to a real problem you choose, on topics such as consumer behaviour, household spending, school or neighbourhood issues. It is judged on method, honesty of data and clarity, and not on dramatic findings.

Step 1: Identify the problem and set objectives. Choose a specific, manageable question (for example, 'How do students of Class 11 in our school spend their weekly pocket money?'). Write 2 or 3 objectives (what you will measure) and, if useful, a simple hypothesis. A topic that is too broad cannot be completed.

Step 2: Choose the target group and sample. Define the population (e.g. all Class 11 students) and the sample (e.g. 40 students). Decide the sampling method (random, stratified by section, or convenience, stating its limits) and the sample size you can handle. Mention why the sample represents the population.

Step 3: Collect data. Decide primary or secondary data; for primary, design a short, clear questionnaire, pilot test it with a few respondents, correct it, then run the survey. Keep the original sheets. For secondary data use reliable published sources and note them.

Step 4: Organise and present data. Tally and tabulate; make frequency distributions for numerical data; present with tables, bar or pie diagrams, histograms or line graphs. Give each table and diagram a number, title and source.

Step 5: Analyse and interpret. Use suitable tools: averages (mean, median, mode), percentages, correlation, index numbers. State results in words with reference to the objectives. Be careful with causation.

Step 6: Conclusions, suggestions and bibliography. Summarise findings, answer the objectives, mention limitations (sample size, possible bias), give suggestions and list sources (books, reports, websites) and acknowledgements.

Report layout. Cover page; contents; introduction and objectives; methodology (sample, tools); data presentation; analysis; conclusions; limitations; bibliography; appendix (questionnaire).

Ethics. Take consent, keep respondents anonymous, report honestly, give credit to sources.

Flow chart: problem → objectives → sample → questionnaire → pilot → survey → table/diagrams → analysis → conclusions.

How to answer Steps of a Statistical Project questions

Questions ask to plan a project, justify a step or critique a design.

  1. 1State the objective in one clear sentence.
  2. 2Define population and sample with method and size.
  3. 3Describe the questionnaire and pilot test.
  4. 4Choose tables and diagrams that fit the data type.
  5. 5List conclusions and limitations honestly.

Steps of a Statistical Project in real life

The idea, met in an everyday situation. Answer the question in your own words, then compare with the model answer. The one-line hook is what to remember.

Class snack survey

Suppose a Class 11 group wants to study what students buy from the canteen in a week.

List the steps they should follow and the main tools they will use.

Try it first, then show the solutionSolution
  1. Objective: find the most-bought items and average spending.
  2. Sample: 40 students from all sections; questionnaire pilot-tested on 5.
  3. Tabulate, draw a bar diagram of items, find mean spending, then conclude and give suggestions.

Answer: Problem, sample, questionnaire, tabulation, averages and diagram, conclusions.

Memory hook: Plan before you count.

Tricks to remember Steps of a Statistical Project

Short memory aids. Say each one aloud once, then use it on a question the same day.

Steps of a Statistical Project: solved examples

Ordered from board level to HOTS. Try each one before you open the solution.

Example 1: Objectives · 2 marks · Very short answerBoard level

Write two clear objectives for a project on the pocket money of Class 11 students.

Try it first, then show the solutionSolution
  1. To find the average weekly pocket money of the students (1 mark).
  2. To find what share is spent on food, travel and others (1 mark).

Answer: Average and pattern of spending.

Example 2: Sample design · 3 marks · Short answerBoard level

Define the population and propose a sample design for a school survey of 300 Class 11 students. State the size and method.

Try it first, then show the solutionSolution
  1. Population: all 300 Class 11 students (1 mark).
  2. Sample: 30 students (10 per cent) (1 mark).
  3. Method: stratified random selection from each of the sections, proportionately (1 mark).

Answer: 300; 30; stratified random.

Example 3: Questionnaire test · 3 marks · Short answerHarder board level

Explain why a questionnaire should be pilot tested and give two changes that might follow.

Try it first, then show the solutionSolution
  1. To find unclear or leading questions before the main survey (1 mark).
  2. Change: reword ambiguous questions (1 mark).
  3. Change: reorder questions or remove unnecessary ones (1 mark).

Answer: Test, then revise.

Example 4: Choosing presentation · 3 marks · Short answerHarder board level

For each data type choose a table or diagram: (a) share of pocket money on five items (b) distribution of weekly pocket money of 40 students (c) weekly attendance over 10 weeks.

Try it first, then show the solutionSolution
  1. (a) Pie diagram or component bar (1 mark).
  2. (b) Frequency distribution and histogram (1 mark).
  3. (c) Line graph (time series) (1 mark).

Answer: Pie; histogram; line graph.

Example 5: Critique a project · 5 marks · Long answerHOTS / competency

A student surveys 8 friends in her own bench, asks leading questions and concludes that all Class 11 students prefer online classes. Critique the design and propose improvements.

Try it first, then show the solutionSolution
  1. Sample of 8 friends is too small and convenience-based, so it is biased (1 mark).
  2. Leading questions affect the answers (1 mark).
  3. Conclusion is generalised to all Class 11 students without evidence (1 mark).
  4. Improve: larger stratified random sample and a pilot-tested neutral questionnaire (1 mark).
  5. State limitations and avoid claims beyond the sample (1 mark).

Answer: Small biased sample, leading questions, overgeneralisation.

Practice questions on Steps of a Statistical Project

Write each answer on paper first. Open the hint only if you are stuck, and the answer only when you have finished.

  1. Q1 · 1 mark · MCQBoard level

    The first step of a statistical project is
    (a) collecting data (b) identifying the problem and objectives (c) writing the report (d) drawing diagrams

    Hint

    (b).

  2. Q2 · 1 mark · Assertion-reasonHarder board level

    Reason (R): It reveals ambiguous or leading questions before the full survey.
    (a) Both A and R are true and R is the correct explanation of A.
    (b) Both A and R are true but R is not the correct explanation of A.
    (c) A is true but R is false.
    (d) A is false but R is true.

    Hint

    Test run.

    Answer

    (a).

  3. Q3 · 2 marks · Very short answerBoard level

    Why should a project state its limitations?

    Hint

    Honesty.

    Answer

    To show the sample size, possible bias and scope so that readers do not draw conclusions beyond what the data support.

  4. Q4 · 4 marks · Case-basedHarder board level

    Read and answer.
    Suppose a group wants to study how much time Class 11 students spend on screens daily.
    (a) Suggest the target group and sample. (1)
    (b) Name the type of variable. (1)
    (c) Suggest two ways to present the results. (2)

    Hint

    Continuous time.

    Answer

    (a) All Class 11 students; a random sample of about 40. (b) Continuous (time). (c) A frequency table with a histogram, and a bar diagram of average time by section.

  5. Q5 · 3 marks · Short answerHOTS / competency

    Suppose two groups study the same topic; one uses primary data from 50 students and the other uses a published report. Compare strengths and weaknesses and say what each must record.

    Hint

    Primary vs secondary.

    Answer

    Primary data fit the objective and are current but cost time and need a sound sample; secondary data are quick but may not fit or may be outdated. Each must record the method or source, date and limitations.
