In a one-sample test (either a t-test or a z-test), we will typically calculate one test statistic, and then either use that test statistic's critical values or a p-value to determine our conclusion. In a two-sample test, we are comparing means (for example, testing a claim that ...
Test Statistic:The chi-square statistic (chi^2) is calculated by comparing observed and expected frequencies in a contingency table. Degrees of Freedom:In a chi-square test, degrees of freedom are calculated based on the number of categories in each variable. For a contingency table with r row...
{eq}s= 1 {/eq} hours. A test statistic should objectively measure the apparent discrepancy between the sample mean and the population mean, as assumed under the null hypothesis. An appropriate test statistic, for reasons discussed below, is the so-calledz-score of the sample mean, calculated...

As a hypothetical example, assume that an analyst needs to calculate the correlation for the following two data sets: X:(41, 19, 23, 40, 55, 57, 33) Y:(94, 60, 74, 71, 82, 76, 61) There are three steps involved in finding the correlation. The first is to add up all the X...
5 Courses | 29+ Hours of HD Videos | Certificates for each Course Completed The t-test compares only two data groups, but ANOVA can compare three or more groups. T-test uses T-statistic, whereas ANOVA uses F-statistic. The t-test compares two data groups that relate to each other, but...
It also depends on whether a one- or two-tail test is being conducted. For example, if your test sample statistic is greater than the critical score, you can determine your scores as statistically significant, therefore rejecting the null hypothesis. ...
For a test of significance at α = .05 and df = 2, the Χ2 critical value is 5.99. Step 4: Compare the chi-square value to the critical value Is the test statistic big enough to reject the null hypothesis? Compare it to the critical value to find out. Example: Comparing the chi-...
