In probability theory and statistics, the Normal Distribution, also called the Gaussian Distribution, is the most significant continuous probability distribution. Sometimes it is also called a bell curve. A large number of random variables are either nearly or exactly represented by the normal distribution, in every physical science and economics.A statistics problem typically contains four components: 1. Ask a Question. Asking a question gets the process started. It’s important to ask a question carefully, with an understanding of the data you will use to find your answer. 2, Collect Data. Collecting data to help answer the question is an important step in the process.
