TS-6 IGNOU Guess Paper 2026-27

TS-6 IGNOU Guess Paper (Term-End Exam Focus)

This structured guess paper aligns with the official IGNOU CBCS curriculum for TS-6: Time Series Analysis, emphasizing solved previous-year questions (2019–2024) and dynamic scoring patterns. Below are key blocks, time management tips, and subject-specific insights.

Core Syllabus Blocks & Question Weightage

• Unit 1: Introduction to Time Series (15% weightage)
  • Focus on trend decomposition methods (classical vs. STL) with 2–3 numerical questions from past papers.
  • Expect 1 short-answer question on stationarity tests (ADF/KPSS) with Python/R code snippets.
• Unit 3: ARIMA Model Specification (25% weightage)
  • Prioritize differencing strategies and ACF/PACF interpretation (3–4 questions in Dec 2023 session).
  • Practice model diagnostics (Ljung-Box test, residuals analysis) with 1 long-answer question.
• Unit 5: Forecasting & Model Evaluation (20% weightage)
  • Master error metrics (MAPE, RMSE) and their application in exponential smoothing (2022 June paper).
  • Prepare for 1 case study on seasonal ARIMA (SARIMA) with real-world data (e.g., monthly sales data).
• Unit 7: Advanced Topics (SARIMA, State Space Models) (10% weightage)
  • Short-answer questions on Kalman filter basics (2021 Dec session).
  • 1 numerical on interpreting SARIMA(p,d,q)(P,D,Q)s parameters.

3-Hour Exam Time Management

• Allocate 45 minutes to short-answer questions (10 marks each; focus on Units 1, 3, and 5).
• Spend 1 hour 15 minutes on long-answer questions (20 marks; prioritize ARIMA diagnostics and forecasting errors).
• Save 30 minutes for revision—cross-check calculations and rephrase answers for clarity.

Subject-Specific FAQs

• Q: How to differentiate between ARIMA and SARIMA in exams?

  Highlight the seasonal components (P,D,Q)s in SARIMA and provide an example (e.g., quarterly data with seasonal pattern). Use a step-by-step model selection flowchart from Unit 3.

• Q: Are Python/R codes mandatory for numerical questions?

  Partial marks are awarded for logical steps even without full code. Focus on interpretation of outputs (e.g., ACF plots, residuals).

Downloadable PDF Features
