Step 2 Find the critical value(s) from the appropriate table. T-test means use the t-table (Table F). We have 9 degrees of freedom since n 1 =10 and n 2 =10. The smallest of n 1-1 and n 2-1 is 9. Information we need: two-tailed test, =0.05, df=9 T critical value is 2.262 Step 3 Compute the test value and determine the P-value.

The t test evaluates whether the mean value of the test variable (e.g., test performance) for one group (e.g., boys) differs significantly from the mean value of the test variable for the second group (e.g., girls). HYPOTHESES FOR THE INDEPENDENT-SAMPLES t TEST Null Hypothesis: H

Ex. 1 Suppose you want to calculate the critical value of t for a 90% confidence interval with 17 degrees of freedom, i.e. you want to find the value of t* for which 5% of the area under the curve lies above t* and 5% lies below –t*. To find this value using STATA type: . display invttail(17,0.05) in the STATA command window.

The critical value we need to use in this t-test is +1.71. This makes the decision rule for this test… If tX ≥ +1.71, reject HO Our observed value for t is 10.0 so our decision is to reject the null hypothesis and accept the alternative hypothesis. The conclusion sentence that might appear is an APA paper
