Izzy Statistics vs Stats & Probability Calculator

The most complete statistical tool. With an intuitive and simple interface that will facilitate your statistical calculations wherever you are. It doesn't matter if you are a student or a professional, it is just as functional. Enter the numbers of a sample or a population separated by a space, select if the data belongs to a sample or a population, touch the calculate button and you will obtain the result of the following equations: - Ordered numbers - Total numbers - Arithmetic Mean - Median - Mode - Quartiles - Interquartile range - Range - Average deviation - Variance - Standard Deviation - Coefficient of Variation - Typical Values - Atypical Values - Extreme Atypical Values You can also create and get the histogram properties of the data: - Histogram - Lowest and highest data - Distribution Range - Total numbers - Classes Number - Classes Range - Classes Besides you can: - Save the data for future use and not have to enter it every time you need it - Update the data in case you need to add, modify or delete any - Delete the data when you think you no longer need it Do not forget to leave your comment and rating, as well as share the app with your friends. This helps us a lot as we can reach more people. For any question, suggestion, doubt or to report an error, send us an email. We are constantly growing to offer you the best possible app and experience.

Take the frustration out of statistics and probability calculations. Whether you’re a student tackling homework or a professional analyzing data, our all-in-one Statistics Calculator app gives you fast, accurate answers in seconds. No more tedious manual math or searching for formulas – with over 140 calculators across every area of stats, you’ll have the tool you need for any problem at your fingertips. Designed for ease of use and clarity, the app is organized into intuitive categories (Probability, Distributions, Descriptive Stats, and Inference/Test calculators). Simply pick a calculator, input your data or parameters, and get instant results. Complex calculations have never been this simple! Features & Highlights: Comprehensive Toolset: Covers basic to advanced statistics – from means, medians, and standard deviations up to complex regression analyses and hypothesis tests. (140+ calculators in one app!) - Probability & Paradoxes: Calculate probabilities and odds with ease. Solve classic puzzles like Bayes’ Theorem, the Birthday paradox, Monty Hall problem, Bertrand’s paradoxes, and more. Simulate random events with a Coin Flipper, Dice Roller, or even explore lottery odds and false-positive paradoxes. - Statistical Distributions: Work with all the important distributions. Compute probabilities, critical values, and percentiles for Normal, Binomial, Poisson, Exponential, Lognormal, - - - Uniform, and other distributions. Includes tools like a Central Limit Theorem simulator and Confidence Interval calculators for population parameters. - Descriptive Statistics: Instantly get summary stats for your data set. Enter your numbers to see the mean, median, mode, range, and standard deviation (population or sample). - - View 5-number summaries (min, Q1, median, Q3, max) and identify outliers with the IQR and outlier calculators. No data set is too large – let the app do the heavy lifting in moments. - Statistical Tests: Conduct hypothesis tests without tables or tedious calculations. Our app includes t-Tests (1-sample, 2-sample, paired), Chi-Square tests (goodness-of-fit, independence), z-tests, F-tests, and even one-way ANOVA. Just input your sample data or summary stats, and get test results with test-statistics and p-values instantly. - Regression Analysis: Go beyond basic stats – perform regressions and understand relationships in data. The app features Linear Regression (with R² (R-squared) and residual analysis), as well as Polynomial and Exponential regression tools. Determine the line of best fit for your data points and make predictions without needing a complex PC program. - Charts & Plots: Visualize your data for better insights. Create histograms, box plots, dot plots, pie charts, and stem-and-leaf plots on the fly. For any data you input, the app can generate charts so you can see distribution shapes and outliers. Turn raw numbers into a visual story in one tap. - Intuitive UI & Fast Results: No learning curve required – the interface is clean and simple. Calculators are grouped by category, and each comes with clear input fields and labels. Enter your figures and get results immediately, with no internet connection needed. The app is lightweight and works offline, so you can study or work on statistics anywhere. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
