What is Statistics ?
Statistics is the Science of Information.
It includes collecting, processing and interpreting the data. The goal is to draw conclusions or generalities from the collected data.
Example : Batting averages, Average annual rainfall in a region, Average return on the investment etc. This is the information that can be organized and is presented in terms of percentages, proportions, frequency, charts, tables, etc.
The examples above are part of what's called Descriptive Statistics. It can be presented in simple and direct ways and it deals with the finding out the information regarding the data in front of us.
The other technique is what's called Inferential Statistics. In it we try to infer the behavior or generalizations of population or data based on small sample or subset of population. We use the information from our sample to estimate the behavior of larger data, i.e., population.
