Compute the mean absolute deviation (MAD) — the average absolute distance of each value from the mean — alongside the me...
Calculates sample covariance Cov(X,Y) = [ΣXY − (ΣX)(ΣY)/n] / (n−1) and population covariance / (n). Also shows the sign...
Calculates the coefficient of variation (CV) as a percentage to compare variability between datasets with different mean...
Compute probabilities of single events, joint events, and complements using basic probability rules.
Compute the five-number summary (min, Q1, median, Q3, max), interquartile range, and 1.5×IQR outliers from a list of num...
Calculates the confidence interval for a population mean from sample mean, known standard deviation, sample size, and co...
Calculates the required sample size to estimate a population mean within a specified margin of error E at a given confid...
Calculates the chi-square statistic for a 2×2 contingency table to test for independence between two categorical variabl...
Applies Chebyshev's inequality to give a distribution-free bound on the probability of a value lying more than k standar...
Compute the standard error of the mean (SEM) — how precisely the sample mean estimates the population mean — from a list...
Calculate the coefficient of variation (CV) — a unitless measure of dispersion that lets you compare the spread of data...
Calculates the t-statistic for a paired t-test from the mean difference, standard deviation of differences, and sample s...
Compute the arithmetic mean (average), along with the median, mode, sum, and range, of any comma-separated list of numbe...
Calculates the variance and standard deviation of a continuous uniform distribution on interval [a, b].
Computes the Pearson correlation coefficient r from aggregate statistics without raw data: r = [nΣXY − ΣXΣY] / √{[nΣX² −...
Compute the sample covariance, population covariance, Pearson correlation r, and the slope of the regression line from t...
Calculate sample and population standard deviation with variance and z-scores for each value.
Standard deviation is "average distance from the average". That one sentence covers 90% of everything you ever need to remember about it.
