Application of Correlation

For this discussion:

· Identify a research question from your professional life or career specialization that can be addressed by a correlation.

· Indicate why a correlation would be the appropriate analysis for this research question.

· Describe the variables and their scale of measurement.

· Discuss the expected outcome—positive, negative, no relationship.

If correlation does not imply causation, what does it imply? Are there ever any circumstances when a correlation can be interpreted as evidence for a causal connection between two variables? If yes, what circumstances?

Interpreting Correlations

A meta-analysis (Anderson & Bushman, 2001) reported that the average correlation between time spent playing video games ( X) and engaging in aggressive behavior ( Y) in a set of 21 well-controlled experimental studies was .19. This correlation was judged to be statistically significant. In your own words, what can you say about the nature of the relationship?
