9 Real Life Examples Of Normal Distribution The normal distribution is widely used in understanding distributions of factors in the population. Because the normal distribution approximates many natural phenomena so well, it has developed into a standard of reference for many probability problems.

It also makes life easier because we only need one table (the Standard Normal Distribution Table), rather than doing calculations individually for each value of mean and standard deviation. In More Detail. Here is the Standard Normal Distribution with percentages for every half of a standard deviation, and cumulative percentages:
I vote with Peter Flom and Terry Moore that nothing real follows a Normal distribution. What is true is that many quantities are approximately bell-shaped in their centers. These are the examples other answers are citing. The reason for that is th...
What could be good examples of normally distributed variables that I can use to illustrate Normal Distribution? IQ scores and heights of adults are often cited as examples of normally distributed ...
Normal Distribution of Data A normal distribution is a common probability distribution .It has a shape often referred to as a "bell curve." Many everyday data sets typically follow a normal distribution: for example, the heights of adult humans, the scores on a test given to a large class, errors in measurements.
In the normal distribution -- the bell-shaped curve -- the mean (average), median (middle), and mode (highest point) all coincide. The bell-shaped curve fits that description. It also implies that whatever you're studying tends to group toward the center. One classic example is test scores -- at least where the test is well-designed and ...
A normal distribution, sometimes called the bell curve, is a distribution that occurs naturally in many situations.For example, the bell curve is seen in tests like the SAT and GRE. The bulk of students will score the average (C), while smaller numbers of students will score a B or D.
On example of working a normal distribution word problems, involving a lower cut off point. I also use the z-formula and z-table. On example of working a normal distribution word problems ...
NORMAL DISTRIBUTION. History. The normal curve was developed mathematically in 1733 by DeMoivre as an approximation to the binomial distribution. His paper was not discovered until 1924 by Karl Pearson. Laplace used the normal curve in 1783 to describe the distribution of errors.Subsequently, Gauss used the normal curve to analyze astronomical data in 1809.
