Statistics and data analysis involve collecting, analysing, interpreting and presenting data to stakeholders to enhance their decision-making.

Statistics is all about making sense of numbers and finding patterns in the data - in business, health, sports, science, the arts, and more.

Statistics can be divided into two main branches, descriptive statistics and inferential statistics.

Descriptive Statistics summarise and describe the features of a data set.

Inferential Statistics allow us to make predictions or inferences about a population based on a sample of data that we have access to.
