A series of free Statistics Lectures in videos.
These lectures introduce descriptive and inferential statistics and discuss sampling methods.
Descriptive statistics summarizes a sample, giving us some ideas about the mean and spread of the data, etc. Inferential statistics use a sample or samples to describe what the population is like; in other words, infering the characteristics of the population from the sample/s.
