# Wiki Chi-squared clarify.

On the wiki https://wiki.geogebra.org/e... could you update,

ChiSquaredTest( <Matrix>, <Matrix> )

Performs a chi-squared test that compares the given matrix of observed counts against the given matrix of expected counts.

to

ChiSquaredTest( <Observed Matrix>, <Expected Matrix> )

Performs a chi-squared test that compares the given matrix of observed counts against the given matrix of expected counts.

Or at least

ChiSquaredTest( <Matrix>, <Matrix> )

Performs a chi-squared test that compares the first given matrix of observed counts against the second given matrix of expected counts.

Although I would prefer the first fix, so when my students use the ChiSquaredTest( command they will automatically get a reminder of which order to place them.

Same for

ChiSquaredTest( <Observed List>, <Expected List> )

Thanks, good idea!
