Descriptive Statistics

It is all about the following topics:

  • position indexes (mean, fashion, median)
  • dispersion indices (mean square deviation, variance, coefficient variation, etc.)
  • quartiles and quantiles etc ...
  • linear and non-linear regression
  • covariance and correlation coefficient

Inferential Statistics

And this one concerns

  • Combinatorial calculation and definition of probability
  • discrete, continuous and mixed random variables
  • probability mass, density function (pdf) and cumulative distribution function (cdf)
  • Significant probability distributions (Binomial, Uniform, Normal, Poisson)
  • Estimation of parameters (point estimators and confidence intervals)
  • Hypothesis test
  • Transformation of random variables
