When to use independent samples in statistical analysis?
An independent samples t-test is used when you want to compare the means of a normally distributed interval dependent variable for two independent groups. For example, using the hsb2 data file, say we wish to test whether the mean for write is the same for males and females. t-test groups = female (0 1) /variables = write.
Which is the best test for statistical analysis?
Because the standard deviations for the two groups are similar (10.3 and 8.1), we will use the “equal variances assumed” test. The results indicate that there is a statistically significant difference between the mean writing score for males and females (t = -3.734, p = .000).
How to test the hypothesis of partial correlation?
This is related to multiple linear regression. To test the hypothesis about partial correlation you use t -statistic in similar fashion as with regular correlation but with N − 3 degrees of freedom. The same formula can be used for Pearson’s or Spearman’s correlation coefficients (for more see Altman, 1991 or Revelle, n.d. ).
