Applied statistics

Applied statistics is the use of statistics and statistical theory in
real-life situations.

Anyone committed to empirical observation as a means of knowing the universe
about us can apply statistics as a research tool. This obviously includes
science but includes history and arts and entertainment as well. For
example, econometrics makes heavy use of applied statistics to study the economy.

In each of these areas, we need to observe, recognize the potential for
error in our observations, and plan our research to control the
observational error.
