.SPSS Output for an Independent Samples T Test. We first take a look at Group Statistics.First off, note that there’s only a small difference between our sample means.
Analysis of Variance The previous example suggests an approach that involves comparing variances; If variation among sample means is large relative to variation within samples, then there is evidence against H 0: 1 = 2 k. If variation among sample means is small relative to variation within samples, then the data is consistent with H 0: 1 = 2
Pooled methods are applied since the comparison of the largest to smallest sample standard deviation is ? 2 —– 10.85 / 8.41 = 1.29 Again, we would have to first calculate these sample standard deviations so we would know whether to select in Minitab the “Assume Equal Variances”. Step 3: p-value is give as 0.000.

Pooled standard deviation definition and easy to follow examples. How to calculate the pooled standard deviation, plus alternative formulas. Variance and Standard Deviation Calculator; the idea is that you would be able to get a better model for the sampling distribution of the sample
(Of course, because the sample sizes are equal (m = n = 10), the pooled sample variance is just an unweighted average of the two variances 6.3001 and 3.61). Because m = n = 9, if we were to calculate a 95% confidence interval for the difference in the two means, we need to use a t -table or statistical software to determine that:
