In this post, you will be challenged to look at how statisticaltests, such as correlation are commonly used and the possiblelimitations of such analyses. In addition, you will need to identify theappropriate application of course-specified statistical tests, examineassumptions and limitations of course specified statistical tests, andcommunicate in writing critiques of statistical tests.
Much has been written about the relationship between students’ SATtest scores and their family’s income. Generally speaking, there is astrong positive correlation between income and SAT scores. Consider anddiscuss the following questions as you respond:
- What does this correlation tell you?
- Is this correlation evidence that having a high family income causes one to have high SAT scores?
- Is this correlation evidence that high SAT scores are a cause ofhigher income? Or, does this tell you something else? Explain youranswer.
- Explain why correlation alone is rarely sufficient to demonstrate cause.
