Question

correlation between rainfall and population​

Answer 1

Answer:

Population measures more readily correlate with precipitation totals (a direct influence) than with NDVI means (a surrogate measure), though not overwhelmingly so.

Answer 2

The correct answer is option that the correlation between rainfall and population​ is Positive.

Explanation:

• Correlation is a statistical term describing the degree to which two variables move in coordination with one another.
• If the two variables move in the same direction, then those variables are said to have a positive correlation.
• If they move in opposite directions, then they have a negative correlation.
• Population measures more readily correlate with precipitation totals (a direct influence) than with NDVI means (a surrogate measure), though not overwhelmingly so.
• When rainfall has a direct effect on a resource, such as forage for herbivores, the effect of increasing variability in rainfall will be to decrease both the average population growth rate of the herbivore population and the long-run population growth rate.
