Correlation:

Correlation is a technique that help us to find or define a relationship between two variables.  A positive correlation means that an increase in one quantity leads to an increase in another quantity A negative correlation means with increase in one quantity the other quantity decreases. Values between 0 and 0.3 tells about a weak positive linear relationship, values between 0.3 and 0.7 shows a moderate positive correlation and a correlation of 0.7 and 1.0 states a strong positive linear relationship. Values between 0 and -0.3 tells about a weak negative linear relationship, values between -0.3 and -0.7 shows a moderate negative correlation and a correlation value of of -0.7 and -1.0 states a strong negative linear relationship.

Since, as the life satisfaction increases, there is a decrease in the anxiety symptoms. Thus, a coefficient correlation of - 0.5 show a moderate negative correlation between anxiety problems and life satisfaction.

Option C) - 0.5
