Scientific Calculator With Normal/Gaussian Distribution vs Probability Lab

F-Graph calculates and plots the standard normal distribution frequency and density functions. One tail, middle, two tail and cumulative density functions (probabilities) can be calculated together with the raw frequency function. You may enter directly Z values referred to N(0,1), or X values referred to a generic N(m, s). In case of X values, the values for m=mean and s=standard deviation are also required. If Z values are entered, X values are computed according to m and s and the other way around. F-Graph also works as a scientific calculator. You may enter the calculation clicking on the buttons of the application pad or directly directly enter the expression as text. Press = to perform the calculation. The calculator supports multiple level of parentheses. A parenthesis is automatically appended when a function button is pressed. You will have then to enter the argument and the closing brace. Supported functions: ln(X) logarithm base e log(X) logarithm base 10 log2 logarithm base 2 exp(X) e to X rtod radians to decimal degrees dtor decimal dgress to radians sqrt(X) square root of X nthroot(X, N) Nth root of X pow(N, X) N to X all common trigonometric functions. Arguments are entered and returned in radians

Probability Lab is an interactive toolkit for exploring probability distributions and statistical concepts. Choose from a wide range of continuous and discrete probability distributions, including the Normal, Binomial, Poisson, Beta, Gamma, Student's t, Chi-Square, and many more. Instantly compute probability density (PDF), cumulative distribution (CDF), inverse CDF (quantile), and other distribution functions with precise results. Visualize every distribution using smooth, interactive graphs. Adjust parameters in real time and watch the curve update instantly, making it easy to build intuition about how each parameter affects the distribution. Whether you're studying for a statistics course, teaching probability, or simply exploring mathematical concepts, Probability Lab provides a fast, intuitive, and beautiful way to understand probability distributions. **Features** • 15+ continuous and discrete probability distributions • Compute PDF, PMF, CDF, inverse CDF (quantile), and more • Interactive graphs with real-time parameter adjustment • Smooth, high-quality visualizations • Designed for students, educators, and anyone learning probability and statistics For questions or feedback, contact us anytime at chordstudio3572@outlook.com Terms of Use https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
