It covers relevant calculations such as mean, standard deviation, and standard error of the mean (S.E.M.) to evaluate data reliability. Confidence limits are highlighted for assessing the probable range of a population's true mean, typically at a 95% confidence level.

It is important to note that statistics can only be helpful if the data from the sample is representative of the population and the interpretation of the data is unbiased! Quantitative (numerical) data – Data expressed not by means of a natural language description, but rather in terms of numbers.
