*

Calculates the correlation coefficient, a

 

 

 

 

number between －1 and ＋1 that

 

 

 

 

measures how closely the x,y data points

 

 

 

 

match the calculated curve.

 

š

*

Calculates M. For the linear model, this is

 

 

 

 

the slope.

*

Calculates B. For the linear model, this is

œDisplays a choice of the four curve-fitting models:

•, H, I, and ž.

Ÿ! Calculates the weighted mean of the x-values using the weights in the y-list.

! Calculates the standard deviation of a set of x-values grouped by frequencies specified in the y-list.

¡! The number of items in either list.

)

¢! Sum of items in x-list. £! Sum of items in y-list. ¤! Sum of squares of items in x-list. ¥! Sum of squares of items in y-list. ¦! Sum of products of items in x- and y-lists.
