Advanced Probability Distributions
The 10bII+ allows easy calculation of the Z and Student's T probability distribution values. In addition, it allows inverse calculations of both functions. The values are calculated using the lower tail probability. This lower tail probability corresponds to the area under the curve to the left of the input. If you need a value other than a lower tail, such as a

These distribution functions replace the statistical tables found in the back of textbooks. Unlike the textbook, the calculator can calculate any value, not just a limited selection found in the table.
