Normal Distribution | Gaussian Distribution | Bell Curve | Normal Curve - Z TABLE

What is Normal Distribution?Normal Distribution also known as Gaussian Distribution (named after the German mathematician Carl Gauss who first described it) is a continuous probability distribution in which the occurrence of data is more clustered near the mean than the occurrence of data far from the mean. This characteristic lends the normal distribution a bell curve like shape which is symmetric about the mean. Normal distribution is one of the most common types of distribution patterns used in statistics and real life.Examples of Normal DistributionExample 1: Normal Distribution of Test Scores A Normal Distribution can be observed by analyzing the test scores of students for any particular course. A large number of students will score the average score (say 65 out of 100), while a few will score near 50s or 80s and fewer will fail the test or get a perfect score. If the scores of these students were to be mapped on a graph, it would lend itself the shape of a bell curve.Example 2:...
