Averages Calculates different averages to measure the central tendancy of a series : arithmetic mean, median, mode, geometric mean, harmonic mean, quadratic mean, interquartile range (IQR) and cubic mean.
Standard deviation Calculator of the standard deviation of a statistical series for two dataset types : population or sample.
Variance Computing the variance of datasets representing the entire population or a sample.
Descriptive statistics Display a summary or complete statistics for a dataset : size, min, max, mean, median, variance, standard deviation, quartiles, skewness, kurtosis, etc.).
Quartiles and Percentiles Calculates quartiles, deciles and percentiles of a statistical series.
Correlation Covariance of a statistical series calculator (population or sample datasets). Correlation coefficient, coefficient of determination, Kendall correlation and Spearman coefficient.
Linear Regression Linear regression calculations : linear regression line, total sum of squares (TSS or SST), explained sum of squares (ESS), residual sum of squares (RSS), mean square residual, degrees of freedom, residual standard deviation, correlation coefficient, coefficient of determination (R² or r²), regression variance, 95% confidence interval and finally the 95% prediction interval.
Circular statistics Circular statistics calculator : angular mean, the resultant length, the mean resultant length, the angular variance, and the angular standard deviation.
