What is BECS 184 Question Paper December 2025?
The BECS 184 December 2025 question paper is the IGNOU term-end examination for Data Analysis across BAG, B.Com, B.Sc, BAECH, and BAM programmes, covering 100 marks in 3 hours with theory and numerical questions.
This paper is a core statistics and data analysis course at IGNOU. It tests your ability to apply statistical methods, interpret data, and explain analytical frameworks in writing. The combination of theory questions and numerical problems makes it one of the more application-focused papers in the IGNOU undergraduate catalogue, requiring both conceptual clarity and calculation accuracy.
About IGNOU BECS-184 | Data Analysis
BECS-184 is a paper where theory and application are equally tested. That's what makes preparation different from a purely descriptive economics paper. You need to understand measures of central tendency not just as definitions but as formulas with conditions for when each measure is appropriate. The hypothesis testing questions require you to follow a specific sequence of steps, and skipping even one step costs marks.
The syllabus covers measures of central tendency and their inter-relationships, primary data collection methods and sample survey planning, null versus alternative hypothesis and hypothesis testing steps, composite index construction, the difference between bar diagrams and histograms with numerical construction, p-value method in hypothesis testing, correlation versus causation, secondary data sources and limitations, multivariate data analysis techniques, qualitative data analysis methods, coefficient of determination, and short note topics including confidence interval, central limit theorem, random variable, standard error, and types of data.
BECS 184 Exam Pattern and Marks Breakdown
Section A has 4 questions and you attempt any 2, each worth 20 marks. These are longer analytical answers requiring definitions, explanations, and in some cases methodological steps. Section B has 8 questions and you attempt any 5, each worth 12 marks. Here's the important part: Section B includes a numerical question requiring histogram construction from a data table, so you cannot treat this section as purely written. Question 12 in Section B asks for short notes on any 3 from 5 options, giving 4 marks each. Total paper is 100 marks in 3 hours.
All Questions | BECS 184 Question Paper December 2025 IGNOU (Complete List)
Section A: Answer any two questions. (2x20=40)
Explain various measures of central tendency. What is the relationship among mean, median and mode? Point out situations where median and mode are suitable.
(a) Give a brief account of the methods of primary data collection. (b) Explain the steps involved in planning and organization of a sample survey.
Distinguish between null hypothesis and alternative hypothesis. Explain the steps you would follow in testing of a hypothesis.
What is a composite index? Explain how a composite index is constructed.
Section B: Answer any five questions. (5x12=60)
Explain the difference between single bar diagram and histogram. Construct a histogram from the following data:
Scores in numerical ability: 10-20 (Frequency: 15), 20-30 (Frequency: 30), 30-40 (Frequency: 50), 40-50 (Frequency: 35), 50-60 (Frequency: 20)
Explain how p-value method is used in hypothesis testing.
Distinguish between correlation and causation. Explain how cause and effect between two variables (X = cause and Y = effect) can be analysed.
Give a brief account of the sources and the limitations of secondary data.
Briefly describe various techniques of analyzing multivariate data.
Explain the techniques by which qualitative data can be analysed.
Explain the concept and implications of the coefficient of determination.
Write short notes on any three of the following: (a) Confidence interval (b) Central limit theorem (c) Random variable (d) Standard error (e) Types of data
BECS 184 Syllabus Topics Covered
The December 2025 paper covers the full BECS-184 syllabus across both sections. Central tendency with mean, median, and mode relationships is a direct Section A question. Primary data collection and sample survey planning also appear in Section A. Hypothesis testing, both through the step-based method and the p-value approach, is tested in both sections. Index numbers appear as a 20-mark Section A question. Section B covers bar diagrams and histogram construction, correlation and causation, secondary data, multivariate analysis, qualitative analysis, coefficient of determination, and five short note options. Preparing all topics gives you maximum choice across both sections.

Take Question 3 on hypothesis testing. A strong 20-mark answer would begin by clearly defining null hypothesis as the statement of no effect or no difference, and alternative hypothesis as the competing claim. Then it would walk through the steps of hypothesis testing: stating hypotheses, choosing significance level, selecting the appropriate test statistic, calculating the test statistic from data, comparing with critical value or using p-value, and drawing the conclusion. Each step should be explained briefly but precisely. That methodical progression through defined steps is how the BECS-184 solved question paper structures every theory-based Section A answer.
How to Write High-Scoring Answers in BECS 184 Question Paper
For Section A at 20 marks, structure your answer with a clear opening definition, well-separated sections for each part of the question, and where applicable, formulas or conditions. The central tendency question has three parts: explaining measures, their relationships, and suitable situations. Address all three explicitly. For Section B, twelve marks means either four well-made points or a short numerical solution with explanation. Question 5 is purely numerical, so show your histogram construction steps clearly, label the axes, and draw the bars accurately. For Question 12 short notes, aim for four to five sentences per topic, covering definition, key feature, and one application.
Who Should Use This BECS-184 Solved Question Paper December 2025?
This solved paper is useful for students across all five programmes that include BECS-184: BAG, B.Com, B.Sc, BAECH, and BAM. It is especially valuable for students who find the numerical questions on histograms or coefficient of determination challenging, and for those who want to see how theory-based answers on hypothesis testing or correlation should be structured for full marks. Students attempting this paper for the first time or improving on a previous attempt will both benefit from having a complete solved reference that matches IGNOU's format and depth expectations.
Why This is Better Than Free BECS-184 December 2025 Question Paper PDFs
A plain question paper PDF leaves you with the data table in Question 5 and no idea how to construct the histogram correctly, label it, and explain it in writing. It also gives you the hypothesis testing question without showing you which steps to follow and in what order. The Unnati Education solved paper covers every question with the right method, formula, diagram description, or step-by-step numerical solution as required. That is the practical gap between a question paper and a genuinely useful exam preparation resource.
