The Normal Distribution is also called the Gaussian distribution. It is a common continuous probability distribution. In statistics, the normal distributions are used to represent real-valued random variables whose distributions are not known. The normal distribution is sometimes informally called the bell curve. The simplest case of a normal distribution is known as the standard normal distribution. Use the below given calculator to for the calculation of normal or guassian distribution of a set of data.
The mean and standard deviation of a data set is 20 and 35. The random variable value is 5. What is its Normal / Guassian Distribution?
Here , X = 5, which is less than mean.
Hence, M-Z = 20 - 5 = 15
Z = (5 - 15) / 35
