About This Subject
Essential Statistics for Business Analytics (Course Code: COM1MN109) is a quantitative minor for B.Com Semester 1 students at Calicut University under FYUGP 2026. This course equips commerce students with foundational statistical tools required to analyze business data and support evidence-based management decisions. Topics include data collection and classification, measures of central tendency (Mean, Median, Mode), measures of dispersion (Standard Deviation, Variance, Coefficient of Variation), skewness, correlation analysis (Karl Pearson's coefficient, Spearman's rank correlation), regression analysis, and basic time-series analysis.
Key Topics Covered
- Role of statistics in business decision-making, data types (primary vs. secondary), and sampling methods
- Measures of central tendency: Arithmetic Mean, Median, Mode, Geometric Mean, and their properties
- Measures of dispersion: Range, Quartile Deviation, Mean Deviation, and Standard Deviation
- Relative dispersion: Coefficient of Variation (CV) and its application in risk and stability comparisons
- Measures of skewness: Karl Pearson's and Bowley's coefficients of skewness
- Correlation analysis: scatter diagrams, Karl Pearson's correlation coefficient, and Spearman's rank correlation
- Linear regression analysis: regression equations of Y on X and X on Y, regression coefficients, and estimation
- Time-series analysis: components of time series, moving averages method, and trend determination
Learning Outcomes
- Collect, organize, and summarize commercial business datasets using statistical tables and graphs.
- Compute and interpret measures of central tendency and dispersion for business metrics.
- Evaluate relative consistency and risk between business datasets using the Coefficient of Variation.
- Compute Karl Pearson and Spearman rank correlation coefficients to measure commercial relationships.
- Formulate regression equations to forecast business variables and demand trends.
Exam Preparation Tips
Memorize formulas for Standard Deviation (grouped and ungrouped data), Karl Pearson's correlation coefficient, and regression lines (Y on X, X on Y). Show all calculation steps, intermediate table columns (d, d^2, dx*dy), and formula substitutions clearly to earn full marks.
