Question #3 (Correlation):C) is there a relationship between car weight and engine size?

  • Descriptive statistics
  • Discuss the data
  • Include a table of summary statistics
  • Include a chart(s) that effectively display the data
  • Show the regression line and equation in the chart of data
  • Explain the regression equation (slope and y-intercept)
  • Discuss the coefficient of correlation and determination

Inferential statistics – test the significance of the least squares regression model (follow the

  • procedures in the textbook)
  • Null and alternative hypotheses
  • Level of significance (why this level?)
  • Critical values (explain how you got them)
  • Test statistics (classical method and p-value method)
  • Test requirements met?
  • Display formulas and intermittent calculations through final answer (so instructors can
  • see where in the process an error was made, if any).
  • Test conclusion (compare test statistic with critical value)
  • Interpretation Statement (see textbook for examples) Confidence intervals

 

Conclusion

Summary of the analyses and ideas for future tests or research.

 

Lessons Learned

Provide comments on the group project (interest in the subject matter, interaction among

members, value of project, ideas for improvement)

 

Comment on any other part of the statistics course that you enjoyed or would like to see

improved.
