Are you doing math with an abacus? No? Well, why are you using Z-score tables? Enter the mean and standard deviation of a bell curve, and this application computes the area under the curve to the left of any value you specify.

Or, compute the value on a bell curve given the area beneath it.

"Statistics Pro" contains a rich collection of solvers, examples, and tutorials for the following topics:

- Data analysis (mean, standard deviation, 1st quartile, median, 3rd quartile, and outlier thresholds for up to 30 data values)
- Linear regression (best-fit line and correlation coefficient on up to 30 points)
- Chebyshev's Theorem
- Normal Distributions
- Chi Squared Distributions
- Poisson Distributions
- Exponential Distributions
- T-Tests for One and Two Means
- Confidence Intervals
- Uniform random number generation
- Binomial random number generation
- Gaussian random number generation
- Poisson random number generation
- Exponential random number generation
