Definition of statistics

Statistics can be defined as the science involved in the study of data. It entails collection (acquisition), organization and analysis of data which allows for drawing of conclusions. It also allows for measuring, controlling and communication of uncertainty (Witte & Witte, 2010).

Types and level of statistics

There are two types of statistics, namely: descriptive and inferential statistics. Descriptive statistics quantitatively describes features of a set of data represented numerically. It involves summary of the population data numerically or pictorially/graphically thereby deriving measures of central tendency, measures of dispersion, relationship and correlation and measures of Skewness and kurtosis (Witte & Witte, 2010). Inferential statistics entails studying a statistical sample and from it infer population parameters and model relationships within the data. Such statistics allow for estimation of population values based on sample data, developing mathematical relationships and hypothesis testing.
