What is Normal Distribution?
Normal distribution is usually shown with the bell-shaped curve. The mean/average is in the middle as a large bump and on either side of this sides slope downward. It is to show the distribution of data. You can find more information here: ... Read More »

How to Calculate Normal Distribution
When applying statistical modeling to a set of data, the "normal distribution" refers to a bell-shaped probability function that is centered around the mean value of the sample. Once constructed, this function allows researchers to evaluate... Read More »

How to Calculate Probability and Normal Distribution
Calculating probability requires finding the different number of outcomes for an event---if you flip a coin 100 times, you have a 50 percent probability of flipping tails. Normal distribution is the probability of distribution among differe... Read More »
