Statistics

I have to do a statistical analysis project at work, so I decided to brush-up on my statistics. Here are my notes.

Descriptive and interential statistics

Statistics can be divided into two large fields: descriptive and inferential. Descriptive statistics takes a bunch of data, and summariezes it in a way that turns the data into information. Inferential statistics makes predictions about an entire population based on data collected from a sample of that population.
