My TI 83 calculator does NOT show the correlation coefficient (r and r2)
May someone please advise why my TI 83 does NOT display the correlation coefficient? I've also check the website and was unable to find help. Please HELP.
So here are the steps that I am refering to:
CALC menu
#8 (LinReg (a+bx)
ENTER
I get:
LinReg
y=a+bx
a=1.1360
b=.2380
But I don't get the r2= or the r=
Is there something that I need to setup in the options or mode? Please help Thank you.
