## SF comments

(1) General. If I understand this function correctly, then it is calculating the area under the chi-square probability density function curve to the right of the specified chi-square value. If this is correct, would it be worth stating?
(2) 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”.
(3) Summary. Would it be worth having “(observed value-expected value)^2/expected value” as a Math equation rather than inline text?
(4) Summary. Should the words “right-tailed” appear somewhere in this summary?
(5) Arguments, 1st bullet point. Should “or” appear before “equal”? Also spurious space before final full stop.
(6) Arguments. 3rd bullet point. Change “in an” to “to an”.
(7) Arguments. Case where DegreesFreedom is not a number at all not covered.
(8) Arguments. I am confused by the equation and the Wikipedia link - both refer to the chi distribution rather than the chi-square distribution.
(9) Examples. Please remove spelling errors from the second example – “Chis” and “randome”. Also change second occurrence of “value” to “values”.
