## Description

The creators of 5-star Scientific++ and Statistics Calculator++ redesigned Statistics Calculator+++ exclusively for iPad.

In designing the statistics functions of this app we had one thing in mind: The user should not need to read a single line of manual to perform the statistical analysis.

Simply use Add X, Add Y, and Add f buttons to enter the elements of the lists and frequencies, if any. And you are done. All the statistics and regression models are only a few swipes away. Press the List button to see the lists entered. The elements of the lists are interpreted independently (as two separate lists) and jointly for regression analysis (if the size of the lists are equal).

The sum, mean, population standard deviation, sample standard deviation, sample variance, sum of squares, min, max, quartiles, and sum of multiplications of two lists are presented in a table. Each statistics measure can be chosen from the table and used for further calculations.

For regression analysis linear regression, logarithmic regression, exponential regression, power regression, and quadratic regression (In-App Purchase) are calculated. Statistics Calculator+++ has an extremely simple and intuitive user interface to choose the regression model and calculate predictions for x and y values and view residuals and residual sum of squares.

Other major features of Statistics Calculator+++ are:

- Shows the expression as you enter and keeps a history of your calculations
- Capability of performing fraction manipulations and converting between different formats (proper, improper, and mixed fractions) and seamless integration of fraction, integer, and decimal manipulations.
- Capability of inputting degrees, minutes, and seconds for angles and converting between degrees-minutes-seconds format and decimal format.
- Capability of calculating permutation, combination, Least Common Multiple (LCM), Greatest Common Divisor (GCD).
- Quadratic and system of two linear equations solver
- Rectangular to polar and polar to rectangular coordinate conversion (extremely useful for phasor calculations for electrical engineers)
- Throws a set of dice (choice of 1 die to 4 dice)
- Backspace to delete last digit entered.
- Sinusoidal functions can be calculated for angles in units of degrees, radians, or gradians.

You are going to love the simplicity of the user interface and yet have the powerful functionality with which Statistics Calculator+++ is loaded.

### The manual on the website is really clear!

The Legend!!!!!!!

I started messing around with all of the different functions, and the manual on the developers website was a great way to do this. Not sure if some of the other commenters here made the effort to go online, so definitely take a look.

The developers are pretty responsive with any issues too.

Very helpful statistics calculator. Just plug in the numbers and all you need is right there and if you wanna get more advanced and see the regression models and do interpolation, a few button presses and swipes will do the trick. The results are also very accurate, never had seen any problems with this app. Thanks developers.

### Simply brilliant

For a while, I was looking for a calculator specialized in statistics to help me with design of experiments. I just found one which has all I needed. Besides the wonderful price, accurate functioning, implementing variety of regression analysis models and professional interface design adds more value to this simply brilliant app.
