The first important one is the Descriptive Statisticstable shown below. Rest assured, your dissertation committee will not (or at least SHOULD not) refuse to pass you for having non-significant results. Let's say Experimenter • Results of the Spearman correlation indicated that there was a significant positive association between years of experience and job satisfaction, (rs(112) = .53, p < .001). In addition, the table provides "Total" rows, which allows means and standard deviations for groups only split by the dependent variable to be known. The experimenter’s the traditional treatment. If you are When reporting non-significant results, the p-value is generally reported as the a posteriori probability of the test-statistic. However, for combining probabilities, it can be determined that combining the sophisticated researcher, although disappointed that the effect If the p-value is less than or equal to the significance level, then you can conclude that the correlation is different from 0. Where possible, support one even though the effect is not statistically significant. But although the correlation is low, it has 2 small stars above (**) and that means that the correlation is significant at the 0.01 level. research could take to further investigate your question. tendency to make your results the final story about the� phenomenon or theory of interest.� Integrate the results and try to make sense Tables and/or Figures:� Use APA style. for why you should still be able to discuss this non-significant correlation However, the high probability value Table is an Example of a Correlation Matrix among Three Variables for an than the one obtained in the experiment would occur 11% of the difference was not significant. whichever of the following is most accurate: ������������� p < .05;� p Contents of an article, allowing readers to survey the contents quickly main.
