What is BEY 014 Question Paper December 2025 Definition
The BEY-014 December 2025 question paper is the official IGNOU Term End Examination paper for Statistical Methods, conducted in December 2025 for BSCAEY students. It carries 70 marks, runs for three hours, and asks you to attempt any seven questions of equal marks, with a scientific calculator permitted.
The paper tests your grip on applied statistics for energy and science students. You are expected to handle measures of central tendency, correlation, regression, skewness and kurtosis, time series trend and components, and conceptual questions like primary versus secondary data, class limits, class mark and tally bar with clear tables and formulas.
About IGNOU BEY-014 Statistical Methods
BEY 014 is a core paper in the IGNOU BSCAEY programme. It gives you the statistical base that later supports energy audit, data analysis and research related subjects. The course covers classification and tabulation of data, measures of central tendency and dispersion, skewness and kurtosis, correlation and regression, and time series analysis including moving averages and trend. It also covers data sources, primary and secondary, and basic terms like class limits, class mark, tally bars and open end classes that appear in tabulation.

BEY 014 Question Paper December 2025 Syllabus Topics Covered
The paper maps cleanly to the BEY 014 syllabus. You see measures of central tendency through simple and weighted arithmetic mean, and median and mode from frequency distribution with missing frequencies. Correlation is tested through Spearman's rank correlation. Regression is tested through two lines of regression for a bivariate data set. Skewness and kurtosis appear both as theory and as a proof of Pearson's inequality. Time series is covered through three year weighted moving average and the four components T, S, C, I. Conceptual topics include primary and secondary data, class mark, class limits, open end classes and tally bars.

Take Question 3 on rank correlation. A weak answer applies the formula directly without a working table. A scoring answer first writes Spearman's formula rho equals 1 minus 6 sigma d square by n times n square minus 1. Then it makes a table of ranks R1 and R2, finds d equals R1 minus R2, computes d square, sums them, substitutes with n equals 8, and finishes with the final correlation value along with interpretation. Our solved paper shows every row of this table clearly.
How to Write High-Scoring Answers in BEY 014 Question Paper December 2025
For every numerical, always follow the same order, given data, formula, working table, substitution, final answer with units or interpretation. For missing frequency problems like Question 2, use both median and mode formulas to set up two equations, plus the total frequency equation, and solve the three unknowns step by step. For regression, compute means, deviations and then both Y on X and X on Y lines. For theory, draw neat skewness curves and time series components. Keep tables neat, use margins, and box every final answer.
Who Should Use This BEY-014 Solved Question Paper December 2025?
This solved paper is made for IGNOU BSCAEY students appearing in June 2026, December 2026 or later Term End cycles. It also helps reappear candidates, backlog students clearing BEY 014, and working professionals from energy audit firms, data analytics teams, and research based organisations who have joined BSCAEY as a career skill. If you are balancing duty hours, family and studies, this paper gives you a focused, time saving way to revise without opening every chapter of the statistics block from start again.
Why This is Better Than Free BEY-014 December 2025 Question Paper PDFs and Telegram Files
Free PDFs on Telegram and random blog sites often have wrong numerical answers, missing tables, or theory that does not match IGNOU BSCAEY style. Some files skip the missing frequency question entirely. Others give one paragraph for a 10 mark regression problem, which will clearly not score. Our solved paper is written by a subject expert, checked against the official December 2025 paper, and formatted in proper statistics answer style with full working tables. You save time, avoid confusion, and protect your marks fully.
Student Reviews BEY-014 Solved Question Paper by Unnati Education
Aman from Lucknow, a working data analyst, said the rank correlation table format matched exactly how his office reports run their numbers. Deepika from Raipur told us the two regression lines answer for Question 5 finally helped her understand Y on X versus X on Y. Karan, a first time BSCAEY learner from Jammu, wrote that the skewness and kurtosis proof was the clearest explanation he had read online during his full preparation cycle for this statistical methods paper.
