P-value: How to use chi square test calculator for testing population variance Two tailed Calculate Results Test Statistics $\chi^2$: Degrees of Freedom: $\chi^2$-critical value(s): left-tailed, right-tailed or two-tailed.)Ĭhi Square test Calculator for variance Population Standard Deviation ($\sigma$) Sample Size ($n$) Sample Standard Deviation ($s$) Level of Significance ($\alpha$) Tail : Left tailed The chi square test calculator for testing population variance makes it easy to calculate the test statistic, chi-square critical value and the p-value given the sample information, level of significance and the type of alternative hypothesis (i.e. We will discuss some numerical examples using six steps approach used in hypothesis testing to test hypothesis about the population variance or population standard deviation. To test the claim about the population variance or population standard deviation we use chi-square test. In this tutorial we will discuss a method for testing a claim made about the population variance $\sigma^2$ or population standard deviation $\sigma$.
