Probability and Statistics > Descriptive Statistics
Statistics can be broken down into two areas: descriptive statistics — which describes and summarizes data, and inferential statistics — which uses statistics to make predictions. Descriptive statistics just describes data. For example, descriptive statistics about a college could include: the average SAT score for incoming freshmen; the median income of parents; racial makeup of the student body. It says nothing about why the data might exist, or what trends you might be able to see from the data.
Descriptive statistics can be further broken down into several areas, like:
The charts, graphs and plots site index is below. For definitions and information on how to find measures of spread and central tendency, see: Basic statistics (which covers the basic terms you’ll find in descriptive statistics like interquartile range, outliers and standard deviation).

There are literally dozens of charts and graphs you can make from data. which one you choose depends upon what kind of data you have and what you want to display. For example, if you wanted to display relationships between data in categories, you could make a bar graph.
A pie chart would show you how categories in your data relate to the whole set.
Scatter plots are a good way to display data points.
