I am doing a study on locus of control and coping ability moderated by social support. For the subscale of locus of control - internal belief, it was found that there were no significant prediction on coping ability when using the linear regression statistical analysis. However, when the internal belief subscale was categorized into high and low levels and tested with a 2 way anova on coping ability, it can be seen that there was a significant main effect. So, how should i report this contrasting find in my research study? It is confusing and I am stuck in the discussion section because of this contrast in results obtained. Please help and advice.

These are actually two slightly different questions:

Regression: Is coping ability linearly related to locus of control-internal belief?

ANOVA: Are people who are high on internal belief different on coping ability than people who are low on internal belief?

Before reporting anything, I would examine plots of the two variables against each other. I'd also take a careful look at whether the assumptions of the models were violated.

Then I might use splines in the regression.

  • $\begingroup$ thank you so much~ now i understand it clearer. :) anyway so to clarify, i can report that internal belief locus of control does not significantly predict coping ability but individuals with high and low levels of internal beliefs have significantly different coping ability levels? $\endgroup$ – Ian May 27 '14 at 18:09

    $\begingroup$ Well, those two statements contradict each other. You have to be careful that regression is only looking at linear relationships; there is probably a nonlinear relationship going on. You are not ready to report yet. $\endgroup$ – Peter Flom - Reinstate Monica May 27 '14 at 18:33
  • $\begingroup$ oh alright. I will try to look it up on how to report this. :) thank you for your time and explanations $\endgroup$ – Ian May 27 '14 at 18:46
