Paste or load your CSV, pick sample or population for the deviation, and read the statistics table generated for every numeric column. Copy the results in one click.
For every numeric column you get the count of valid values, the sum, mean, median, mode, minimum, maximum, range, variance, standard deviation and the Q1, Q2 and Q3 quartiles with the interquartile range. Non-numeric columns are reported as text and skipped.
You can choose. Sample standard deviation divides by n-1 and is the right default when your rows are a sample of something larger; population divides by n and is correct only when you hold every member of the group.
Using the linear interpolation method on the sorted values, which is the same approach as spreadsheet QUARTILE functions, so the numbers match what Excel or Google Sheets would give you for the same column.
