Statistics is a mathematical science pertaining to the collection, analysis, interpretation or explanation, and presentation of data.

Descriptive Statistics

There are 2 main ways of representing descriptive statistics:

1. Numerical statistics
   Some numbers are more meaningful than others. For example, if you are offered a purchase price of $1 for a car on the condition that you also buy a second car, the price of the second car would be a major consideration (its price could be $1,000,000 or only $1,000), and thus, the average—or mean—of the two prices would be the more important statistic.
2. Pictorial statistics
   Taking numerical data and presenting it in pictures or graphs is what is known as pictorial statistics. Showing data in the form of a graphic can make complex and confusing information appear more simple and straightforward.

Inferential Statistics

Inferential statistics are usually the most important part of a dissertation's statistical analysis. Inferential statistics are used to allow a researcher to make statistical inferences, that is draw conclusions about the data.

There are two main types of Inferential Statistics:

1. Estimation
2. Hypothesis testing
