WebbThe grade is 65. Well first, you must see how far away the grade, 65 is from the mean. So 65 will be negative because its less than the mean. 65-81 is -16. Divide that by the standard deviation, which is 6.3. So -16 divided by 6.3 is -2.54, which is the z score or "the standard deviation away from the mean. WebbOne of the most widely used curves in statistics is the normal curve given by where μ is the population mean and σ is the population standard deviation. This tutorial is about …

WebbThe value on the y axis just denotes the value of the probability density function evaluated at different values of x. In the center of the top of the bell curve, a line drops straight down which is the y axis. The bell curve (Gaussian) is a standard bell curve, meaning it is used to measure other things.
