### What is statistics?

Statistics is a branch of mathematics focused on the collection, analysis, and interpretation of data. Data sets can include full population data, surveys, smaller random samples, qualitative data, and much more. Statisticians can apply a number of data analysis techniques to better understand what the data means and how different data points or data sets relate to each other. For example, a pollster can conduct surveys on voter sentiment to determine which issues are likely driving voters to the polls. They can also use statistics to determine how closely their sample of voters reflects the larger population.
