parameters of interest = , the average memory score using Ginkgo, and , the average memory score using placebo. Step 2: significance level is usually taken to be =0.05. Step 3: test statistic = Step 4: p-value = Step 5: Conclusion: Since the p-value < significance level, we reject and conclude that Ginkgo does improve the memory score. 1 5

Here t* is the value for density curve with area C between –t* and t*. To test the hypothesis ,compute the pooled two-sample t statistic. In terms of a random variable T having the t( distribution, the P-value for a test of against . is P() is P() is 2P() Example 5. Take Group 1 to be the calcium group and Group 2 to be the placebo group.

Now in the output below, we can see the results for the T-test. Look at the enlarged numbers under the column that says “t” for the t-value, “df” for the degrees of freedom, and “Sig. (2-tailed) for the p-value. (Notice that the p-value of .539 is greater than our “.05” alpha level, so we fail to reject the null hypothesis.

For critical score work: one of the cutoffs is t* and the total area is α. For P-value work: the upper cutoff is |tsam| and the area is the P-value. This is what TINV and TDIST were built for—area in the two tails, total. t* = TINV(α, n – 1) P-value = TDIST(| tsam |, n-1, 2)

To interpret the t-test results, all you need to find on the output is the p-value for the test. To do an hypothesis test at a specific alpha (significance) level, just compare the p-value on the output (labeled as a “Sig.” value on the SPSS output) to the chosen alpha level. Alternatively, you could just report the p-value, rather than ...

The one-sample t statistic is. The P-value is found from the t(19) distribution (n-1=20-1=19). Table D shows that 3.86 lies between the upper 0.001 and 0.0005 critical values of the t(19) distribution. The P-value lies between 0.0005 and 0.001. Software gives the value P=0.0053. “The improvement in score was significant (t=3.86, df=19, p=0 ...

The t-test for Equality of Means yields a p-value of .089, which informs us that the mean difference of 19.1667in blood pressure between the two groups was not statistically significant at the two-tailed alpha = .05 level. We note that a larger sample size or a one-tailed test might/would give different results. Paired Samples T-Test
