What if the value we created for the Kruskal wallis test to test against x squared critical value is a negative number? What did I do wrong here?
Here the test statistic H is based on squared values. So it is not possible to have a negative value for that. It may be possible that you have done some calculation mistake. I recommend you to do all the mathematics from the beginning in a fresh paper.
Another thing the critical value can't be a negative a chi-squared distribution takes only positive value in its range. I would suggest you to use a calculator to do all the maths, and while calculating the chi-squared critical value you can use a chi-squared table or refer some online chi-square critical value calculator.
