Respuesta :
The correct option is a) -0.15.
The weakest correlation relationship between two variables is given by -0.15.
What is correlation?
With the aid of correlation, the strength of the relationship between two variables can be determined. We can tell from this study whether there is no correlation, weak correlation, or a strong correlation between the two variables.
Two different types of correlation exist:
- positive correlation: Two variables that move together, or in the same direction, are said to have a positive correlation. When one variable rises while the other rises or when one variable falls while the other falls, there is a positive correlation.
- negative correlation: When two variables are correlated negatively, the other variable's value falls as the value of the first variable rises. The correlation coefficient, which expresses correlation on a scale from +1 to -1, is used. Values less than 0 indicate a negative connection.
The correlation value (r) always lies between -1 and 1.
