Statistical Calculations (SD, REG)
Normal Distribution (SD)
Use the key to enter the SD Mode when you want to perform a calculation involving normal distribution.
(SD)
In the SD Mode and REG Mode, the key operates as the
key.
Press (DISTR), which produces the screen shown below.
Input a value from to
to select the probability distribution calculation you want to perform.
Example: To determine the normalized variate (t) for x = 53 and normal probability distribution P(t) for the following data: 55, 54, 51, 55, 53, 53, 54, 52
(t = -0.284747398, P(t) = 0.38974 )
