This beta distribution generator and visualizer lets users set alpha and beta, generate samples, and view histogram/PDF output. It supports reproducible seeded mode and CSV/JSON/PNG export. The tool runs fully in-browser and is free to use.
ToolDone’s Benford calculator checks whether your numeric list aligns with first-digit Benford distribution. It includes practical sample datasets and statistical interpretation guidance, including chi-square based conformity context. The tool is openly accessible with no required paid subscription.
Creating visual representations of categorical data becomes straightforward with an online pie chart maker. Users input their data points as labels and corresponding values to instantly generate a proportional circle graph. This visualization helps in identifying the relative size of different components within a whole, making complex datasets easier to interpret at a glance. Developers and data analysts often use these visualizations to present distribution patterns or survey results within project documentation. The interface allows for quick adjustments to labels and values, ensuring that the final chart accurately reflects the underlying data. By simplifying the graphing process, it serves as an efficient resource for those needing a fast, reliable way to communicate data proportions without manually calculating angles or using complex software.
Generates box-and-whisker plots for your dataset, providing a graphical analysis of central tendency, dispersion, and outliers. By inputting data values, users can visualize quartiles, median, minimum, and maximum values in an intuitive format. Helps users quickly assess statistical properties of their datasets, making it ideal for researchers, students, and professionals needing to understand the distribution and variability in their data.
Use this Weibull distribution calculator if you need find probabilities, quantiles, etc. in the Weibull distribution, or generate samples from this distribution.
Calculator to compute the confidence interval or margin of error of a sample based on the desired confidence level. It also provides an error bar diagram.
