Question

Which best describes the strength of the model? a weak positive correlation a strong positive correlation a weak negative correlation a strong negative correlation.

Answer 1

Correlation coefficient helps us to know how strong is the relation between two variables. The strength of the model is a strong positive correlation.

What is the correlation coefficient?

The correlation coefficient helps us to know how strong is the relation between two variables. Its value is always between +1 to -1, where, the numerical value shows how strong is the relation between them and, the '+' or '-' sign shows whether the relationship is positive or negative.

• 1 indicates a strong positive relationship.
• -1 indicates a strong negative relationship.
• A result of zero indicates no relationship at all, therefore, independent variable.

Hence, the strength of the model is a strong positive correlation.
