Creators of #1 Statistics Calculator on iPhone bring Statistics Calculator++ to macOS.

Statistics Calculator++ is a scientific calculator with statistical, regression analysis (including graph) and probability distribution calculations and graph capabilities.

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 and graphs are only a few clicks and swipes away. Tap 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 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.

You have the capability to add multiple lists and use any of them as list X, list Y, or list f. Access Lists Editor feature by tapping the icon on top right of the Statistics Lists view. Furthermore, all these lists persist in the memory. Therefore, if you close and the relaunch the app the lists are there for you.

Normal distribution functionality of TI-83 or TI-84 (normalpdf, normalcdf, invNorm, ShadeNorm), Student's t-distribution (tpdf, tcdf, invT), Chi-Squared distribution, F distribution, Binomial distribution (binompdf, binomcdf), Poisson distribution (poissonpdf, poissoncdf), and Geometric distribution (geometpdf, geometcdf) are all possible with this app with an easy to use, and beautiful user interface.

Confidence interval calculation and step by step explanation for "One Population Proportion", "Difference in Two Population Proportions", "Population Mean", and "Difference in Population Means".

Hypothesis test for "Population Proportion", "Difference in Two Population Proportions", "Population Mean" and "Population Mean Difference" with known and unknown population standard deviations.

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), and prime factorization.

- 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.

- Showing the content of memory on MR button, as long as it fits.

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