Table T1 Area Under Standard Normal Curve

(Values in the table is the shaded area)

 

Note: This standard normal table gives the percentage under one-half of the normal curve at different Z values. Thus, for Z = 0.0, the value in the table is 0.5 and not 1.0. Normal distribution is symmetrical. Thus the area to the left of Z = –1 equals 0.1587 which is the same as the area to the right of Z = 1.
