Descriptive Statistics

It is all about the following topics:

• Frequency distributions
• graphs of frequency distributions
• 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
