Convert a value to a z-score, find normal-distribution probabilities and p-values from z, or get the z-score for any percentile.
Open tool โInference
Find a confidence interval for a mean (t or z, from summary statistics or raw data) or a proportion (Wald and Wilson), with the margin of error and working.
Open tool โInference
Get the p-value for a z, t, or chi-square test statistic, one- or two-tailed, and see whether it's significant at your chosen ฮฑ.
Open tool โInference
Calculate Cohen's d, Hedges' g, and Glass's ฮ for two groups from their means, standard deviations, and sizes, with the pooled SD and an interpretation.
Open tool โInference
Work out how many people you need for a survey (with margin of error and population size), to estimate a mean, or to compare two groups with a given power.
Open tool โInference
Fit a least-squares line to x, y data: slope, intercept, r, Rยฒ, the slope's p-value, predictions, and a scatter plot with the fitted line.
