One and Two Tailed t Tests Conduct a test of hypothesis about a population mean. <em>One</em> <em>and</em> <em>Two</em> <em><em>Tailed</em></em> t Tests
The two-tailed t-test is performed if the results would be interesting in either direction. The choice of a one- or two-tailed t-test effects the hypothesis testing procedure in a number of different ways. Comparison of One and Two-tailed t-tests.

Hypothesis Testing Upper-, Lower, and Two Tailed Tests Alternative names are one-sided and two-sided tests; the terminology "tail" is used because the extreme portions of distributions, where observations lead to rejection of the null hypothesis, are small and often "tail off" toward zero as in the normal distribution or "bell curve", pictured above rht. <strong>Hypothesis</strong> Testing Upper-, Lower, <strong>and</strong> <strong>Two</strong> <strong><strong>Tailed</strong></strong> Tests
