For example, the value for Z=1.96 is P (Z < 1.96) =. Find a value representing the area to the left of a negative Z score in this. Then, go to the row with 1.5, and go to the column. To find the area to the left of z 1.53, first, break up the number 1.53 into two parts, the first is 1.5, and the second is. As z-value increases, the normal table value also increases. Find a value representing the area to the left of a positive Z score in this standard normal distribution table. The z-table has areas expressed as decimals rounded to 4 places, not percents.
