# Data, Probability, and Statistics

Data, probability, and statistics is a branch of mathematics that deals with collecting, organizing, analyzing, and interpreting numerical data to help understand or predict events or to help come up with an intelligent decision. It is one of the topics included in the GED Math test.

The GED Math test checks how well you analyze, think, and solve real-life problems involving numbers. Naturally, you can expect to find data, probability, and statistics questions on the GED Math test as this subject can be applied to a wide variety of everyday events. You will also find it on many other subjects like social sciences, economics, accounting, banking, and communication.

For example, the information you get from weather forecasts or the amount you pay for insurance is all based on statistics. The medicines sold at the pharmacy have also undergone tests that involved probability and statistics before it was decided that they are safe to be released to the public. The way research companies predict who will win the elections are also based on statistics.
