  1. Presentation of Statistical Data; Population and Sample; Sampling methods; Population parameters
  2. Objective of multivariate statistical analysis; Data, objects, variables and scales (Stevens's classification); Classification of multivariate techniques, Summarizing, describing and graphical representation of multivariate data
  3. Measures of central tendency (mean, median, mode); Measures of dispersion (standard deviation, variance, quantile, and IQR), Statistical inferences. Correlation coefficient. Linear correlation
  4. Hypothesis testing; Type of errors; Parametric hypothesis testing; Sampling distributions, Tests for means (one and two sample tests - matched pairs and independent); t-test
