Frequently Asked Questions
What separators can I use between numbers?
Commas, spaces, and new lines all work. The parser splits on whitespace or commas, so pasted rows or columns usually work without cleanup.
What happens to bad tokens like N/A or text labels in the list?
They are ignored, and the tool tells you how many invalid tokens it skipped. Valid numbers still calculate normally.
Why does it show both population and sample variance and standard deviation?
It calculates both versions so you can compare them without re-entering the data. That is useful because sample-vs-population is one of the most common stats mistakes.
How are quartiles handled for an odd number of values?
The numbers are sorted, Q2 is the median, and the median is excluded from the lower and upper halves before Q1 and Q3 are calculated.
Why does it say No mode when every number appears once?
This tool only reports a mode when at least one value repeats. If all frequencies are 1, it treats the dataset as having no mode.
