Unit 1: Introduction to Business Statistics

This unit introduces fundamental concepts of business statistics, including data types, collection methods, and basic statistical tools. Key topics include:

• Descriptive Statistics: Measures of central tendency (mean, median, mode) and dispersion (range, variance, standard deviation).
• Data Representation: Use of tables, graphs (bar, pie, histogram), and charts for effective visualization.
• Probability Basics: Definitions, axioms, and applications in business decision-making.

Sample Answer (500 words): Explain the importance of descriptive statistics in business decision-making with examples from retail or manufacturing industries. Include a step-by-step calculation of the mean and standard deviation for a given dataset.

Unit 3: Probability Distributions

This unit explores probability distributions, focusing on discrete and continuous distributions. Key topics include:

• Binomial Distribution: Probability of success/failure in repeated trials.
• Normal Distribution: Characteristics, properties, and applications in quality control.
• Poisson Distribution: Modeling rare events in business (e.g., customer arrivals).

Sample Answer (250 words): Compare and contrast the binomial and normal distributions with real-world business scenarios. Provide a solved example of calculating the probability of a Poisson event.

Unit 5: Index Numbers

This unit covers the construction and interpretation of index numbers, essential for economic and business analysis. Key topics include:

• Types of Index Numbers: Price, quantity, and cost-of-living indices.
• Methods of Construction: Simple aggregate, weighted aggregate, and Laspeyres/Paasche indices.

Unit 7: Time Series Analysis

This unit delves into time series data, decomposition techniques, and forecasting methods. Key topics include:

• Components of Time Series: Trend, seasonality, cyclical, and irregular variations.
• Forecasting Models: Moving averages, exponential smoothing, and ARIMA.
• Applications: Sales forecasting, demand planning.

Sample Answer (250 words): Describe the steps involved in decomposing a time series into its components. Apply the moving average method to forecast future sales for a given dataset.

Unit 9: Statistical Quality Control

This unit focuses on statistical techniques for quality assurance in manufacturing and services. Key topics include:

• Control Charts: X̄-R and p-charts for process monitoring.
• Acceptance Sampling: Single and double sampling plans.
• Six Sigma Concepts: Definitions, roles, and applications in quality improvement.

Sample Answer (500 words): Explain the role of control charts in maintaining process stability. Provide a case study on how a manufacturing firm uses p-charts to monitor defect rates.
