Statistics tables for Google Sheets™, laid out like the tables of the Analysis ToolPak in Microsoft Excel: the same row labels, order and statistics, so course instructions, textbooks and answer keys read the same in your spreadsheet.

NINETEEN ANALYSES
- Descriptive Statistics: mean, standard error, median, mode, standard deviation, sample variance, kurtosis, skewness, range, minimum, maximum, sum and count, the Kth largest and smallest, and the confidence level for the mean.
- Histogram: frequencies for your bins, Pareto order, cumulative percentage and a chart.
- Correlation and Covariance: the matrix of two or more columns or rows.
- Rank and Percentile: each value's rank and percent rank.
- t-Test: Paired Two Sample for Means, Two-Sample Assuming Equal Variances, and Two-Sample Assuming Unequal Variances, with one- and two-tail p-values and critical values.
- z-Test: Two Sample for Means with known variances, and F-Test Two-Sample for Variances.
- Anova: Single Factor, Two-Factor With Replication and Two-Factor Without Replication, with each group's summary, F, the P-value and F crit.
- Regression: one or more X columns, R Square, the ANOVA table, coefficients with standard errors, t Stat, P-values and confidence intervals; residuals, standard residuals and the probability table, with residual, line fit and normal probability plots.
- Moving Average and Exponential Smoothing, with standard errors.
- Random Number Generation: uniform, normal, Bernoulli, binomial, Poisson, patterned and discrete, with a seed to repeat a run.
- Sampling: periodic or random.
- Fourier Analysis: the fast Fourier transform and its inverse, of real or complex values.

CHECKED NUMBERS
StatFill computes its own t, F and normal distributions. Every table is checked against R and high-precision reference values before each version is released; random numbers and random samples are checked against their distributions.

YOUR DATA STAYS AS IT IS
StatFill reads the ranges you choose and writes each table to a new sheet, or to an Output Range you pick. It never writes over the data it analyzes, and never over filled cells without asking you first. It reaches only the spreadsheet you open it in.
