An ecologist records soil salinity s s\,s mS cm−1^{-1}−1 and maximum grass height h h\,h cm at 10 sites. Nine points follow a strong negative linear pattern. The tenth point, Site Omega, lies well above this pattern. For the other nine sites, the correlation coefficient is -0.824.
Interpret the value -0.824 in context.
Explain why Site Omega should not automatically be deleted.
State the likely effect on the magnitude of the correlation coefficient if Site Omega is included, and justify your answer.
