Statistics App: descriptive indices, histograms, samples and inference.
This statistics application allows you to quickly and accurately calculate the main descriptive statistical indices of central tendency (mean, median and mode) and dispersion (variance, standard deviation and range). In addition, it constructs automatic histograms based on the Sturges formula to graphically represent the data. The app also includes tools to calculate the necessary sample size based on parameters such as variance, maximum allowed error and confidence level, for both finite and infinite populations. It incorporates an acceptance sampling module by attributes based on standard norms (such as ISO 2859-1), ideal for quality control applications. Finally, it performs statistical inference tests, allowing hypotheses to be contrasted based on the data collected. All in an intuitive interface, adapted for academic users, professionals and students of statistics, engineering and quality.
