It also determines the correlation coefficient and t value, and calculates the extent of the relationship between x and y. pp|z6 b=)(x)(y)i1n)(x)i1n |H a=Ùb v|W t=rn21r | a:intercept e b:slope of the line n:size of sample (n3) r:correlation coefficient r:coefficient of determination @STAT[EXE]8Pack*?( @GUIDETKEYLOG((NOTEP&%&222222xz |The following shows the meaning of each item in the case of list data specification.
