The table found below is a compilation of areas from the standard normal distribution, more commonly known as the bell curve. The table provides the area of the region located under the bell curve and to the left of a given *z* score. These areas represent probabilities and have numerous applications throughout statistics.

Anytime that a normal distribution is being used, a table such as this one can be consulted to perform important calculations. If you need help reading the table, begin with the value of your *z* score. In order to use this particular table, the value should be rounded to the nearest hundredth. Find the appropriate entry in the table by reading down the first column for the ones and tenths places of your number, and along the top row for the hundredths place.

For example, if *z*=1.67, then you would split this number into 1.67 = 1.6 + .07. The number located in the 1.6 row and .07 column is .953. Thus 95.3% of the area under the bell curve is to the left of *z*=1.67.

The table may also be used to find the areas to the left of a negative *z* score. To do this, drop the negative sign and look for the appropriate entry in the table. After locating the area, subtract .5 to adjust for the fact that *z* is a negative value.
