Detail:

ANOVA - Analysis of Variance - Features:

Intra-class Correlation Calculator for ANOVA
One-Way ANOVA Calculator
From Summary Data - supply number of subjects, mean and standard deviation
From Detail Data - supply data within a group and keep adding groups
From Data File - supply tab delimited file.

Beta Function:

Beta Function Calculator
Incomplete Beta Function Calculator
Regularized Incomplete Beta Function Calculator

Scientific Calculator (Infix notation):

18 Basic Arithmetic Operations
Ability to specify and perform fractions
5 Probability Operations
4 Memory Operations
13 Trigonometry operations
5 Statistics functions + data repeat
Specify significance and precision
Autometic precedence and ability parenthesis

Covariance & Correlation:

Covariance and Correlation by entering data. Data sets need to appear column wise. When a row is added, the data points for all the groups in the same position are added.
Covariance and Correlation from file
Covariance from correlation
Correlation from covariance
Significance of correlation

Effect Size:

Effect Size - Hierarchical Multiple Regression
Effect Size - Multiple Regression
Effect size Student's t-Test: Calculates the (two-tailed) effect size for Student's t-test (Cohen's d), given the mean and standard deviation for two independent samples of equal size.

Error Function:

Computes the value of the error function (a.k.a the Gauss error function) evaluated at a value of x. The value returned will be the error function evaluated along the integral from zero to x.
Computes value of the complementary error function. Error function evaluated along the integral from x to positive infinity.

Gamma Function:

Gamma Function
Incomplete Gamma Function
Regularized Incomplete Gamma Function

Probability:

5 Probability Density Function (PDF) functions
3 Cumulative Density Function (CDF) functions
a. Fisher F-Distribution
b. Normal distribution
c. Standard Normal Distribution
9 p-Values + 5 inverse
a. Chi-Square test
b. Correlation Coefficient
c. Fisher F-test & inverse
d. Fisher' Exact Test
e. Normal - cumulative, 1 & 2-Tailed & inverse
f. Student T-Test & inverse

Simple and Multiple Regression:

Calculates simple and multiple regression

4. Draws graphs for simple regression

Solver (with reverse Polish post-fix notation calculator):

Solves f(x)
Value of f(x) at c
fc clears fx
Cij supplies coefficient
20 Basic Arithmetic functions
