Stats on Calculator

I have a Casio fx-991ES PLUS calculator and am looking for a way to get it to calculate stat coefficients for me.

I can get it into Stat Mode, and then type in the relevant data, but from there, how do I get the value of:

a) r, the PMCC
b) rs, Spearman's rank coefficient
c) the coefficients a and b for the regression line of y on x (such that y=a-bx)
d) the coefficients c and d for the regression line of x on y (such that x=c-dy)

Thanks :smile:

Edit: a) and c) have been answered. b) and d) still unanswered.

i have just started a stats module, i have a Casio also so it should be pretty similar although i can only help with the points for a and c. Once you have gone into stats mode on the calculator and A+BX, put in your data values and then press AC, the values will be kept in the memory of the calculator, then press shift and the |-STAT-| button (where the number 1 button is)
pressing 2)data will bring the table back up
Selecting 'reg' will give you options for r, the pmcc, A and B also for the line

i am honestly not sure about find rs, but maybe you can reverse the table values and change the x and y in the table (it might be tedious though) to find the c and d value you are looking for? sorry it is just an idea

Thank you, that's a good start. :smile:

We've got a) and c). By the way are you sure r is PMCC rather than Spearman's rank? I'm worried about the notation the calculator might be using ... (I think we can assume it will be the same between our Casios)
