Presentation Transcript

  1. The Environmental Thread Arctic Sea Ice Examined in Statistics

  2. Arctic Sea Ice

  3. The Data

  4. Data Analysis • Use Arctic Sea Ice Data for construction of: • Histogram • Line Plot • Box Plot (examine for outliers)

  5. Histogram Describe the distribution

  6. Plot Versus Time Does there appear to be a trend?

  7. Box Plot Are there any outliers?

  8. Revisit Data Later • Create a scatter plot • Determine the LSRL • Examine r^2 • Examine r • Examine residual plot

  9. Revisited Data Is a linear model appropriate?

  10. Re-revisit Data Even Later • Inference about the slope for association • Null: Β = 0 (no association between year and MSK’s of arctic ice) • Alternative: Β < 0 (The MSK’s of arctic ice is significantly decreasing over time)

  11. And the Winner of the Statty Is…

  12. Along The Way • Students will be asked to research the causes of the reduction of arctic ice • Students will be asked to research the environmental impact of the reduction

  13. Presumed Ancillary Conversations • Global Warming, I mean Climate Change, will be the primary reason for the reduction. • Animal population of arctic wildlife such as polar bears, penguins, and seals will undoubtedly be listed as points of impact.

  14. So What? • Climate change will allow my class to explore average global temperature and CO2 levels over time. CO2 levels will allow us to explore data straightening techniques • Populations usually follow exponential models, which will allow us to further explore data straightening techniques

  15. Moving Forward • Compare arctic sea ice levels with CO2 • Compare arctic sea ice levels to animal populations • Are problems a result of human fossil fuel consumption?
