Normal probability plot example
WebFor example, the following probability plot shows the pulse rates of test subjects as they walked on a treadmill. For a normal distribution with a mean and standard deviation equal to the data, we would expect 5% of the population to have a pulse rate of 54.76 or less. Note. WebThe normal probability plot is formed by plotting the sorted data vs. an approximation to the means or medians of the corresponding order statistics. Done us...
