Bell curves has some key characteristics that we need to know : Say we're considering the adult male population in France which follows a normal distribution with mean height μ = 175 cm μ = 175 cm and standard deviation σ = 7 cm σ = 7 cm and an adult male is randomly selected from the population.
Why is a normal distribution called a bell curve?
The normal distribution is often called the bell curve because the graph of its probability density looks like a bell. It is also known as called Gaussian distribution, after the German mathematician Carl Gauss who first described it. Normal distribution Vs. Standard normal distribution?
What is a 'bell-shaped' curve of the standard normal distribution?
This is the "bell-shaped" curve of the Standard Normal Distribution. It is a Normal Distribution with mean 0 and standard deviation 1. It shows you the percent of population: It only display values to 0.01% You can also use the table below. The table shows the area from 0 to Z.
