FAQ
How does the calculator clean pasted data?
The parser detects delimiters, converts decimal separators, removes thousand markers, and skips invalid tokens. The step log reports how many values it removed.
Which quartile and histogram rules are available?
You can choose Tukey hinges, inclusive (Type 7), or exclusive (Type 6) quartiles. For bins, Auto tries Freedman-Diaconis, then Scott, then Sturges. You can also set a manual bin count.
When should I change the quartile rule or histogram bins?
Change the quartile rule when you need to match a textbook, spreadsheet, or classroom convention. Change histogram bins when the automatic rule hides structure or creates too many empty bars for the dataset size.
Why might this summary differ from spreadsheet software?
Differences usually come from quartile definitions, sample versus population standard deviation, or how invalid cells and delimiters were cleaned during import. Compare those settings before assuming the formulas disagree.
How should I judge whether the displayed statistics are trustworthy?
Check the step log and teacher notes first. They tell you how many values were parsed, dropped, or transformed. If the imported data were cleaned in an unexpected way, fix the input before trusting the summary numbers or charts.
