Note: While single-variable statistical calculation is selected, you can input
the functions and commands for performing normal distribution calculation
from the menu that appears when you perform the following key operation:
11(STAT/DIST) 5(Distr). See “Performing Normal Distribution
Calculations” for details.
To input the single-variable data x = {1, 2, 2, 3, 3, 3, 4, 4, 5}, using
the FREQ column to specify the number of repeats for each items
({
x
n ; freq n } = {1;1, 2;2, 3;3, 4;2, 5;1}), and calculate the mean and
population standard deviation.
