Data is all around us. Statistics are used to make sense of this data and apply this information to make informed decisions.
Data is often numerical such as weights, temperatures, and dollars. For example, you might be interested in census data or cost of living during a particular year. However it can also take the form of patterns, images, or signals. In general, the purpose of collecting data is to provide information to archive for later use or apply to an immediate question or problem.
Data becomes information when it is organized in a framework that is useful.
Statistics is a type of information derived from mathematical operations applied to numeric data. For example, census data can be used to create statistics such as the average age of city residents. Earthquake data can be used to identify the most common location of earthquakes or the highest magnitude earthquakes through history.
Statistics can be used to address questions and provide evidence to make informed decisions.
