TwoVar
STAT CALC menu
(TwoVa shows on menu)
TwoVar xList , yList , frequencyList
Performs two-variable statistical analysis on the real
data pairs in xList and yList, using the frequencies in
frequencyList
.
Values used for xList, yList, and frequencyList are
stored automatically to the built-in variables
xStat ,
yStat , and fStat , respectively.
TwoVar xList , yList
Uses frequencies of 1.
TwoVar
Uses xStat , yStat , and fStat for xList, yList, and
frequencyList . These built-in variables must contain
valid data of the same dimension; otherwise, an error
