Paste numbers separated by spaces, commas or new lines - a column copied from Excel works - and see the count, sum, mean, median, mode, range, minimum, maximum, geometric and harmonic means, and population and sample standard deviation and variance. Switch to weighted mode for one "value, weight" pair per line, such as grades and credit hours.
A comma is read as a thousands separator only in a properly grouped number like 1,250 when your values are on separate lines or separated by spaces; otherwise commas separate values. You can force either reading. A dot is always the decimal point, and anything that is not a number is listed as skipped rather than silently dropped.
