• Descriptive Statistics
• Measures of central tendency: mean: arithmetic mean, weighted arithmetic mean; geometric mean, harmonic mean, median and mode
• Measures of dispersion: range, quartile, deciles, percentiles, mean deviation, standard deviation and coefficient of variation
• Measures of skewness: Pearson’s coefficient of skewness, product coefficient of skewness

1. ### Probability

• Set Theory
• Definition
• Types of sets
• Set description; enumeration and descriptive properties of sets
• Venn diagrams (order – Venn diagrams precede operation of sets)
• Operations of sets; union, intersection, complement and difference
• Probability Theory and Distribution
• Probability Theory
• Definitions; event, outcome, experiment, sample space, probability space
• Types of events: elementary, compound, dependent, independent, mutually exclusive, exhaustive, mutually inclusive
• Laws of probability; additive and multiplicative laws
• Conditional probability and probability trees
• Expected value, variance, standard deviation and coefficient of variation using frequency and probability
• Application of probability and probability distributions to business problems
• Probability Distributions
• Discrete and continuous probability distributions Z, F, test statistics (geometric, uniform, normal, t distribution, binomial, Poisson and exponential and chi-square)
• Application of probability distributions to business problems
1. ### Hypothesis Testing and Estimation

• The arithmetic mean and standard deviation
• Hypothesis tests on the mean (when population standard deviation is unknown)
• Hypothesis tests on proportions
• Hypothesis tests on the difference between two proportions using Z and t statistics
• Chi-Square tests of goodness of fit and independence
• Hypothesis testing using R statistical software
1. ### Correlation and Regression Analysis

• Correlation Analysis
• Scatter diagrams
• Measures of correlation – product-moment and rank correlation coefficients (Pearson and Spearman) using R software
1. ### Regression Analysis

• Simple and multiple linear regression analysis
• Assumptions of linear regression analysis
• Coefficient of determination, standard error of the estimate, standard error of the slope, t and F statistics
1. ### Time series

• Definition of time series
• Components of time series (circular, seasonal, cyclical, irregular/ random, trend)
• Application of time series
• Methods of fitting trend; freehand, semi-averages, moving averages, least-squares methods
• Models – additive and multiplicative models
• Measurement of seasonal variation using additive and multiplicative models
• Forecasting time series value using moving averages, ordinary least squares method and exponential smoothing
1. ### Linear programming

• Definition of decision variables, objective function and constraints
• Assumptions of linear programming
• Solving linear programming using graphical method
• Solving linear programming using simplex method (basic scenarios)

### 8. Decision Theory

• Definition
• Decision-making process
• Decision-making environment; deterministic situation (certainty)
• Decision making under risk – expected monetary value, expected opportunity loss, risk using the coefficient of variation, the expected value of perfect information
• Decision trees – sequential decision, the expected value of sample information
• Decision making under uncertainty – maximin, maximax, minimax regret, Hurwicz decision rule, Laplace decision rule.
