Statistics Calculator

Today, I would like to present a comprehensive basic statistics calculator that offers a range of essential functions. This calculator is designed to assist users in performing various statistical calculations. Let's dive into its impressive features:

• Descriptive Statistics: This function provides valuable insights into your dataset, including the median, quartiles, standard deviation, variance, coefficient of variation, and standard error.
• Linear Regression: With this feature, you can obtain regression coefficients and equations, which are indispensable tools for analyzing relationships between variables.
• Binomial Distribution: This function offers calculations for mathematical expectations, probability distributions, variances, and deviations within the binomial context.
• Poisson Distribution: Users can employ this tool to explore the fascinating aspects of the Poisson distribution.
• Frequency Distribution: The frequency distribution function allows you to organize and analyze your data by displaying the frequency of each value or range.
• T-Test - One Sample: By utilizing this feature, you can conduct hypothesis testing with ease. It covers important aspects such as H0 and H1 hypotheses, critical regions, test calculations, completion of the test, and p-values.
• T-Test - Two Samples: This powerful tool assists users in comparing two independent samples by analyzing their mean differences.
• Chi-Squared Test: With this function, you can explore the relationship between categorical variables and assess their statistical significance.
• Normal Distribution: Understand the characteristics of the normal distribution with this helpful feature.

In addition to these exceptional functions, this calculator also provides a detailed breakdown of all the formulas used. By referencing this information, users can gain a deeper understanding of the calculations performed.

I extend my sincere gratitude to my brothers, Dhiego and Leandro, for their invaluable assistance in the design and translation of this remarkable tool.
