Malaria is a leading cause of infectious disease and death worldwide.It is also a popular example of a vector-borne disease that could be greatly affected by the influence of climate change.The table below is a summary from a linear regression that uses dewpoint (°C)to predict malaria prevalence in West Africa. Fill in the blank.The correlation coefficient,r,is ___.

Correlation Coefficient

A statistical measure that calculates the strength and direction of a linear relationship between two quantitative variables.

Malaria

A disease caused by a plasmodium parasite, transmitted by the bite of infected mosquitoes.

Dewpoint

The temperature at which air must be cooled, at constant pressure and water vapor content, for it to reach saturation and produce dew.
