Statistics Calculator+++ is a scientific calculator with statistical, regression analysis, probability distributions, confidence intervals, and hypothesis tests 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 are only a few taps 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). You can also take advantage of a new import feature to bring in your data from Microsoft Excel or Apple Numbers by first converting them into .csv format.
Statistics measure and plots:
- Sum, mean, population standard deviation, sample standard deviation, sample variance, sum of squares, min, max, quartiles, and sum of multiplications of two lists are .
- Box and whiskers plot, histogram of the data, linear, area, scatter plot, and moving average.
Regression:
- Linear, logarithmic, exponential, power, and quadratic regressions. 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. It also graphs the regression model and how it fits around the data entered.
You have the capability to save multiple lists of data 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/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. In addition you have Beta and Gamma Distributions.
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:
- The left pane scrolls to reveal more functionality without a need to switch modes.
- You see the expression as you enter and it 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.
This is an ongoing project and we are working on more features and functions to be added to every update of the app.
You are going to love the simplicity of the user interface and yet have the powerful functionality with which Statistics Calculator+++ is loaded.

Good deal

This is an affordable way to get a great calculator! I have both the iOS and iPadOS versions. I like how he has adapted the calculator for iPad.

Great

Couldn’t be happier with a statistics calculator. Does all I need and more.

The manual on the website is really clear!

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.

Where are the statistics?

I assume somewhere on this there are statistical functions, however I don't see them and have been unable to figure out how to find them. How do I get my $1.99 back.

No manual = no good

It is statistically impossible to be able to figure this app out without a manual.

N-1

It's a fine buy, but for class, my instructor teaches the standard deviation with n-1 instead of just n. It would be helpful to have that feature.

Simply Does not Work

It's very simple: try using, e.g., nPr function. How do you use it? I assume this is permutations. But what key do you press first? 5 or the function key? How do you clear the register so you can enter a new problem? I would think by hitting "C" or "MC" or something logical like that. Oh, perhaps the problem is that I don't know how to use it? Where is the manual? Can't find it on the web site. And, IT CRASHES.

Thanks, but.

I like it, but could you put variations as well.

So helpful

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.

Brilliant

Absolutely a charm to do statistics calculations with this app. Hardcore calculations done very precisely, haven’t seen a single fault, yet very artistically and beautifully designed interface that flows from page to page. Just hit buy, you won’t regret it.
