• The standardization conversion formula is as follows:
t =
x − x
—
σx
Notes:
• P(t), Q(t), and R(t) will always take positive values,
even when t < 0, because these functions follow the
same principle used when solving for an area.
• Values for P(t), Q(t), and R(t) are given to six decimal
places.
