Copy and Paste your work from StatCrunch into your Word document submission. Verbally describe the direction and magnitude of the relationship. IV: systolic DV: diastolic Positive strong linear relationship. When the systolic (IV) goes up diastolic (DV) also goes up. 14. Compute the correlation coefficient (Pearson’s r ) in StatCrunch to summarize the relationship for the data presented in Exercise 13. How accurate was your description? Correlation between Systolic and Diastolic is: 0.90936143

Correlation is above positive strong. It’s above 0.75< r 15. Below are Global carbon dioxide concentrations and the measured change in Global temperature (Temperature Anomaly) for an 11 year period in our recent past: YEAR CO 2 Concentration (ppm) Temperature Anomaly (ºC) 1981 339.93 .043 1982 341.13 .022 1983 342.78 .097 1984 344.42 .074 1985 345.90 .091 1986 347.15 .066 1987 348.93 .267 1988 351.48 .155 1989 352.91 .267 1990 354.19 .509 1991 355.59 .430 Using StatCrunch, construct a scatterplot that shows the relationship between the two variables (carbon dioxide concentrations and the measured change in Global temperature). Calculate the r value using StatCrunch. Copy and Paste your work from StatCrunch into your Word document submission. Verbally describe the direction and magnitude of the relationship you find. What does this tell you about Global warming?
The direction is Positive strong Correlation between co2 conc and temp anom (C) is: 0.86758467

###### "Before using Course Hero my grade was at 78%. By the end of the semester my grade was at 90%. I could not have done it without all the class material I found."
— Christopher R., University of Rhode Island '15, Course Hero Intern

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
