there is a subtle difference between the two. Critical values are all maxima, minima, or points of inflection. On the other hand, critical points are sometimes defined as a point in the function’s domain where the function is not differentiable or equal to zero. Like many terms...
Critical Value The use of a chi-square table that we will examine is to determine a critical value. Critical values are important in bothhypothesis testsandconfidence intervals. For hypothesis tests, a critical value tells us the boundary of how extreme a test statistic we need to reject the ...

Unless your goal is to somehow improve on what is already written, or you simply don't have those existing tools, then you should never be reinventing the wheel. Use existing code, for example, regress is in the stats toolbox. Or you could even use my polyfitn fr...

Bureau of Labor Statistics as a good starting point. Down the line, you might also find internal data just as useful. You can turn to your own sales reports and see what trends took off right under your nose.This combination of primary and secondary research can help you create a thorough...
Use the formula to calculate the chi-square value. Find the critical chi-square value using a chi-square value table orstatistical software. Determine whether the chi-square value or the critical value is the larger of the two. Reject or accept the null hypothesis. ...
This post is not trying to replicate a statistics course though so for more details on the actual calculation try starting atWikipedia. Using the Chi-Squared Test on Net Promoter Score Data The chi-squared test is sensitive to shifts in the underlying values making up the NPS, not just the...
