Paste a column of numbers, instantly see what doesn't fit.
A single bad data point — a fat-fingered entry, a sensor glitch, a shipment logged twice — can quietly wreck an average or a forecast. Catching those before they cause damage usually means opening a notebook and writing a few lines of stats. This tool does the same check in one paste, using two standard methods (Z-score and IQR) so you can sanity-check any number list in seconds.
