What it does
GraphPad QuickCalcs provides statistical calculations for categorical data, continuous data, distributions and interpretation of p-values.
QuickCalcs offers focused browser statistics separately from Prism. Its two-sample t-test starts with raw observations or mean, SD/SEM and N; changing entry format erases the data already entered. The form supports up to 50 manual rows or 2,000 pasted rows. Paired testing requires individual values, with each group in its own column; summary data require all three statistics for both groups. All offered test options produce two-tailed results. The guide identifies normality, independence and pairing/variance choices as assumptions to check. Results include P, test statistics and confidence information, while this tool does not graph the t-test.
