Sum of List Elements Sum()
Finds the sum of all elements in a list.
Syntax: Sum(List n )
List Product Prod()
Finds the sum product of all the elements in a list.
Syntax: Prod(List n )
Cumulative Frequency Cuml()
Calculates the cumulative frequency of the elements of a list.
Syntax: Cuml(List n )
Example: When List 1 = {2,3,6,5,4}, Cuml(List 1) = {2,5,11,16,20}
Data Percentages Percent()
Calculates the percentage of each element relative to the sum of all elements in a list.
Syntax: Percent(List n )
List Data Diff ΔList
Calculates {Element 2 − Element 1, Element 3 − Element 2, ... Element n − Element n −1} in a list of n ( n ≥ 2)
elements and returns the result in list form.
Syntax: ΔList a ( a = List variable number)
Note: You can save the result to List 2 by typing "ΔList 1→List 2".
Estimated x-Data x
Estimated y-Data y
These functions are used immediately after performing a regression calculation
value specified for one variable ( x or y ) they, estimate the other variable, based on a regression model.
Syntax: y -value x (Calculates an estimated x -value for the y -value.)
x -value y (Calculates an estimated y -value for the x -value.)
* Estimated values cannot be calculated for the following types of regression model: Med-Med Regression,
Quadratic Regression, Cubic Regression, Quartic Regression, Sinusoidal Regression, Logarithm
Regression.
Sample Standard Deviation StdDev()
Finds the sample standard deviation of data specified by a list.
Syntax: StdDev(List n [,List m ]) (List n ... Sample data, List m ... Frequency data)
Example: StdDev({10,20,30,40},{3,5,4,1}) = 9.26808696
Population Standard Deviation StdDev_σ()
Finds the population standard deviation of data specified by a list.
Syntax: StdDev_σ(List n [,List m ]) (List n ... Sample data, List m ... Frequency data)
Unbiased Variance Variance()
Finds the unbiased variance of data specified by a list.
Syntax: Variance(List n [,List m ]) (List n ... Sample data, List m ... Frequency data)
Population Variance Variance_ σ
Finds the population variance of data specified by a list.
2
Syntax: Variance_ σ (List n [,List m ]) (List n ... Sample data, List m ... Frequency data)
List to Matrix List→Mat()
Saves list contents to Mat Ans.
Syntax: List→Mat(List n ,List m )
(The number of elements in List n and List m must be the same.)
Example: When List 1 = {2,3,4}, List 2 = {20,30,40}, List→Mat(List 1,List 2) =
2
