Serial Correlation in Regression Analysis. ... the Durbin-Watson test can be inconclusive. The critical values of d for a given level of significance, sample size and number of independent variables are tabulated as pairs of values: DL and DU (a table is provided in “Course Documents/Statistical Tables folder). If the test statistic, d falls ...
Running head: PRACTICAL SIGNIFICANCE
Statistical significance is concerned with whether a research result is due to chance or sampling variability; practical significance is concerned with whether the result is useful in the real world.

The significance test for a Pearson correlation coefficient is not robust to violations of the independence assumption. If this assumption is violated, the correlation significance test should not be computed. SPSS© computes the Pearson correlation coefficient, an index of effect size. The index ranges in value from -1.00 to +1.00.

Significance of a correlation SPSS will not only tell you the correlation between variables, it will also tell you the p value of the correlation. Like all other tests of significance, this tells us how likely we would be to find this degree of relationship, if the two variables are, in fact, not related.
