Jasmine collects data on a random sample of 100 rollercoasters around the country. She collects data on the following: 1) height of highest peak on the coaster (measured in feet; ratio measurement scale) and 2) length of the coaster (measured in feet; ratio measurement scale). She is interested in examining if there is a relationship between the highest peak and length of the rollercoaster. Which statistical procedure is most appropriate to use to test the hypothesis?
A) Pearson correlation coefficient
B) Phi coefficient
C) Spearman or Kendall tau's correlation coefficient

Question

Quizplus · Accepted Answer

The Pearson correlation coefficient is the most appropriate statistical procedure for testing the hypothesis of a relationship between the height of the highest peak and the length of the rollercoaster, as both variables are measured on a ratio scale and the interest is in examining a linear relationship between these two continuous variables.
