2. Summarizing of Data: Data collection, Editing, Coding and Reduction. Tabulation and Cross tabulation - Frequency distributions - Presentation of data, graphics, charts, diagrams, frequency curves, histograms and polygons.

3. Statistical measures: Measures of central tendency, Measures of dispersion and measures of skewness.

4. Introduction to Probability: Concepts and definitions of probability - Classical Relative frequency, subjective and axiomatic. Additive and multiplicative theorems. Statistical independence, Marginal, conditional and joint probabilities. Bayes theorem and its applications.
