dicetest2 vs Stats & Probability Calculator

This simple, free, no In-App Purchases App generates a passphrase/password using the keys and values in the Diceware Passphrase Home Page word list. The app basically throws five dice for you (or 30 for 6 elements) to generate random keys to word values in the dictionary, which can then be joined together to form a complex passphrase. Key numbers are displayed in addition to the words (Values) so that you can compare them with the original Diceware data, if desired. Note: Six possible dice values, taken 5 at a time gives 6^5 = 7776 words in the database. Six PassPhrase words give 7776^6 = 2.2x10^23 possibilities (~1/3 of a mole for chemists)! That is over 2^77 = 1.5x10^23. One can also add personalized "salt" characters and Capitalize selected letters in the passphrase generated here to enable even stronger security, e.g. add every other letter of your spouse's secret nickname, in reverse alphabetical order, with a special character or two thrown in. Be creative! If you’d like a shorter, or longer passphrase possibility use fewer elements, or add multiple clicks. Refer to the The Diceware Passphrase Home Page for comments on the true randomness of computer generated random numbers. Using actual dice for this process is a better way to randomly select passphrase words. However, this app introduces the user to the Diceware concept, its word list(s) and allows you to experiment easily and generate many passphrases. The resulting suggested passphrases are offered without any warranty as to their use.

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/
