How to Calculate the Appropriate Test Statistic and p-Value for the Chi-Square Test for Homogeneity Step 1: Identify the number of populations, k, and the number of levels, ℓ, for the categorical variable. Step 2: Calculate the degrees of freedom using the ...
The Test Statistic for One Population Mean Calculator is a calculator that is used when the variable is numerical and only one population or group is being studied. Let's say that an economist, Economist William German, believes that students who work and go to college only spend, on ...
an approximate chi-square statistic is calculated from the p-value of Fisher’s exact test using the CHISQ.INV function, from which the phi and Cramer’sVeffect sizes can be calculated as described above
Assume a 0.05 significance level for testing the claim that the mean pH of the first stream was less (more acidic) than the mean pH of the control stream. Also, assume the two samples are independent simple random samples selected from normally distributed populations. Calculate test statistic...

Depending on the test you run, you may see other statistics that were used to calculate the P value, including the mean difference, t statistic, degrees of freedom, and standard error. The confidence interval and a review of your dataset is given as well on the results page. ...
