What is the difference between a normal distribution and the standard normal distribution?

What will be an ideal response?

A normal distribution is a bell-shaped distribution defined by two parameters, ? and ?. The values for the mean and standard deviation reflect the population data and may be any values. Thus, a normal distribution may be centered at any value and may have any spread, but it will have the common bell shape. The standard normal distribution is a specific normal distribution with mean = 0 and standard deviation equal to 1.0. The horizontal axis of the standard normal distribution represents z-values. Any normal distribution can be converted to the standard normal by converting the random variable values to z-values.
