- (1) General. We need to be consistent how we write “chi-square”. At the moment this page has spellings with both lower case and upper case “C”; also with and without a hyphen; also with both “square” and “squared”.
- (2) Summary. Is “one-tailed” correct/consistent, or should it be “right-tailed” (as in Returns section)?
- (3) Returns. Presumably the value returned in non-negative?
- (4) Arguments, 1st bullet point. Or not a number at all? Also, is 0 a valid value because =CHIINV(0,5) gives error 502.
- (5) Arguments, 3rd bullet point. Change “in an” to “to an”.
- (6) Arguments. Case where DegreesFreedom is not a number at all not covered.
- (7) Additional details. Insert “the” before “chi”.
- (8) Examples, first example. “one-tailed” or “right-tailed”? Also what is the relation between “=CHIINV(CHIDIST(0.020975769403022;1);1)” and the example cited in the Formula column (which has 5 degrees of freedom)?
- (9) Examples, third example. This is not a great example – the Number is not valid so it probably would not matter what DegreesFreedom was set to.
- (10) Equivalent Excel functions. Incorrect function name.
