Explain the difference between correlation analysis and
regression analysis. Give an example of a lurking variable. If a
statistician computed a value of r = -2.83 what would you tell that
statistician? Under what circumstances can we calculate r? Can the
regression equation be assumed to hold 100 years from now? Are
there other correlation coefficients other than the Pearson Product
Moment Correlation Coefficient
Correlation and Causality: What is meant by the statement that
correlation does not imply causality? Part 2: Cause of Global
Warming: If we find that there is a linear correlation between the
concentration of carbon dioxide (CO2) in our atmosphere and the
global temperature, does that indicate the changes in the
concentration of carbon dioxide cause changes in the global
temperature? Why or why not? Part 3: Application of concepts:
Discuss and give at least one example of how you...
What is the difference between correlation and causation? Offer
an example of each as it relates to healthcare operations
management. Then explain how these concepts are important in
identifying and prioritizing operational improvement
opportunities.
Differentiate between a foundation species and a keystone
species. Give an example of each.
What is an invasive species? Give an example.
What is a pioneer species, and under what circumstances are
these species important?
