Compute the test statistic as {eq}\chi^{2}=c_{1}+ c_{2}+..+c_{k} {/eq} and degrees of freedom {eq}df=k-1 {/eq}, or the number of categories - 1. Compute the p-value for the Chi-Square distribution with {eq}df {/eq} degrees of freedom...
Test Statistic Comparing Two Population Means: This Test Statistic Comparing Two Population Means Calculator calculates the test statistic when comparing two population means. This test is used when the varaible is numerical (for example, cost of goods, earnings, stock price) and two populations or...

The formulas that the calculator uses to compute a T statistic are given at Bartlett's Test for Homogeneity of Variance. What is the P-value? If you assume that the null hypothesis of equal variance is true, the P-value is the probability of seeing a test statistic (T) that is more...
F-Test calculatorcalculates the F-Test statistic (Fisher Value) for the given two sets of data $X$ and $Y$. It's an online statistics and probability tool requires two sets of real numbers or valuables. It is necessary to follow the next steps: ...

1 = 2 using the table, the critical value for a 0.05 significance level with df = 2 is 5.99. that means that 95 times out of 100, a survey that agrees with a sample will have a χ 2 value of 5.99 or less. the chi-square statistic is only 0.7533, so we will ...
The three effect size measures described above can also be used for Fisher’s Exact test. This is straightforward for the odds ratio. For the other two effect size measurements, an approximate chi-square statistic is calculated from the p-value of Fisher’s exact test using the CHISQ.INV fun...
Calculate the test statistics using the formula mentioned above. Calculate P-value. It is the probability of detecting a sample statistic to the level of the test statistic. To derive the probability value, we can use a ‘t Distribution Calculator.’ ...
