Statistics are a set of numbers (quantitative data) obtained through research. For example, the average age of a group of people, or the number of people using a service.
Statistical analysis uses a set of mathematical rules to analyse quantitative data. It can help researchers decide what data means. For example, statistical analysis can assess whether any difference seen between two groups of people (for example between the groups of people in a clinical trial) is likely to be a reliable finding or simply due to chance.
