Statistical Calculations

Example
Store a seed value of 42; set the number display to 9. Then generate three random numbers.
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 two-sided value,
please see the conversion instructions at the end of this chapter.
Table 12-18 Advanced probability keys
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.
