Doing Statistical Calculations (CALC)
Once you have entered a list of numbers, you can calculate the
following values.
For one variable: the total, mean, median, standard deviation, range,
minimum, and maximum. You can also sort the numbers in order of
increasing value.
For two variables: x-estimates and y-estimates (this is also called
forecasting), the correlation coefficient for different types of curves
(this is curve-fitting), the slope and y-intercept of the line, and
summation statistics. You can also find the weighted mean and the
grouped standard deviation.
