Descriptive Statistics + Box Plot & Histogram (with steps)

Q: How does the calculator clean pasted data?

It detects delimiters (comma, semicolon, tab, whitespace) and decimal symbols automatically, removes thousand separators, discards invalid tokens, and records how many points were removed in the step log.

Q: Which quartile and histogram rules are available?

Quartiles support Tukey hinges, inclusive (Type 7), and exclusive (Type 6) definitions. Histogram bins try Freedman-Diaconis first, then Scott, and finally Sturges, or you can override the bin count manually.

Use any delimiter (comma, semicolon, tab, space) and choose between sample or population formulas. Quartiles, histogram bins, and outlier rules are documented step by step so you can cite the method in class or in lab reports.

FAQ

How does the calculator clean pasted data?

It detects delimiters automatically, converts decimal separators, strips thousand markers, and drops any token that cannot be parsed as a finite number. The step log records how many values were removed.

Which quartile and histogram rules are available?

You can switch between Tukey hinges, inclusive (Type 7), and exclusive (Type 6) quartiles. Histogram bins fall back from Freedman-Diaconis to Scott and then Sturges, or you can enter a manual bin count.
