Chapter 12 - Testing for relationships. After reading this chapter, you should be able to: Explain the difference between tests of differences and tests of relationships, use the four analytical steps to design and interpret research designs and statistical findings, know which assumptions of inferential statistics your research project meets and which assumptions it does not meet,. | Chapter 12 Testing for Relationships Tests of linear relationships Correlation 2 continuous level variables Regression 2 or more continuous level variables Identifies statistically significant linear patterns in the association of variables Basic Assumptions Data collected from sample to draw conclusion about population Data from normally distributed population Appropriate variables are selected to be tested using theoretical models Participants randomly selected Alternative and Null Hypotheses Inferential statistics test the likelihood that the alternative hypothesis is true and the null hypothesis is not Significance level of .05 is generally the criterion for this decision If p .05, then alternative hypothesis accepted If p > .05, then null hypothesis is retained Four Analytical Steps Statistical test determines if a relationship exists Examine results to determine if the relationship found is the one predicted Is the relationship significant?
