How do you read a normal probability plot?

A straight, diagonal line in a normal probability plot indicating normally distributed data. A straight, diagonal line means that you have normally distributed data. If the line is skewed to the left or right, it means that you do not have normally distributed data.

How do you find the probability of a normal distribution in Matlab?

y = normpdf( x ) returns the probability density function (pdf) of the standard normal distribution, evaluated at the values in x . y = normpdf( x , mu ) returns the pdf of the normal distribution with mean mu and the unit standard deviation, evaluated at the values in x .

What does a normal probability plot show?

The normal probability plot (Chambers et al., 1983) is a graphical technique for assessing whether or not a data set is approximately normally distributed. The data are plotted against a theoretical normal distribution in such a way that the points should form an approximate straight line.
