A correlation coefficient of 0.15 indicates a weak positive relationship between the two variables. This means that as one variable increases, there is a slight tendency for the other variable to also increase, but the relationship is not strong or consistent. It suggests that other factors may be influencing the variables, and the correlation is not significant enough to imply a definitive link.

What serves as standard of comparison to evaluate effect of the independent variable on dependent variable?

The correlation coefficient, plus graphical methods to verify the validity of a linear relationship (which is what the correlation coefficient measures), and the appropriate tests of the statisitical significance of the correlation coefficient.


What indicates the magnitude of a correlation coefficient?

The magnitude of a correlation coefficient, which ranges from -1 to 1, indicates the strength of the relationship between two variables. A value close to 1 signifies a strong positive correlation, meaning that as one variable increases, the other tends to increase as well. Conversely, a value close to -1 indicates a strong negative correlation, where an increase in one variable corresponds to a decrease in the other. A value around 0 suggests little to no correlation between the variables.


A correlation coefficient represents what two things?

A correlation coefficient represents both the strength and direction of a linear relationship between two variables. A value close to +1 indicates a strong positive correlation, where as one variable increases, the other also increases. Conversely, a value close to -1 indicates a strong negative correlation, where one variable increases while the other decreases. A value around 0 suggests little to no linear relationship between the variables.


What correlation coeficcients expresses weakest degree of relationship?

The correlation coefficient that expresses the weakest degree of relationship is 0. A correlation coefficient of 0 indicates no linear relationship between the two variables being analyzed. Values closer to -1 or +1 indicate stronger negative or positive relationships, respectively. Thus, a coefficient of 0 signifies that changes in one variable do not predict changes in the other.


How would you interpret the findings of a correlation study that reported a linear correlation coefficient of 0.3?

A linear correlation coefficient of 0.3 indicates a weak positive correlation between the two variables being studied. This suggests that as one variable increases, there is a slight tendency for the other variable to increase as well, but the relationship is not strong. It is important to note that correlation does not imply causation, and other factors may influence the relationship. Further research would be needed to explore the nature of the relationship more comprehensively.

When is the correlation coefficient zero?

The correlation coefficient is zero when there is no linear relationship between two variables, meaning they are not related in a linear fashion. This indicates that changes in one variable do not predict or explain changes in the other variable.

Correlation coefficients represents the WEAKEST relationship?

A correlation coefficient represents the strength and direction of a linear relationship between two variables. A correlation coefficient close to zero indicates a weak relationship between the variables, where changes in one variable do not consistently predict changes in the other. However, it is important to note that a correlation coefficient of zero does not necessarily mean there is no relationship between the variables, as non-linear relationships may exist.


What does it mean for variables to show correlation?

A positive correlation coefficient means that as the value of one variable increases, the value of the other variable increases; as one decreases the other decreases. A negative correlation coefficient indicates that as one variable increases, the other decreases, and vice-versa.


What is the meaning of correlation coefficient?

The correlation coefficient takes on values ranging between +1 and -1. The following points are the accepted guidelines for interpreting the correlation coefficient:0 indicates no linear relationship.+1 indicates a perfect positive linear relationship: as one variable increases in its values, the other variable also increases in its values via an exact linear rule.-1 indicates a perfect negative linear relationship: as one variable increases in its values, the other variable decreases in its values via an exact linear rule.Values between 0 and 0.3 (0 and -0.3) indicate a weak positive (negative) linear relationship via a shaky linear rule.Values between 0.3 and 0.7 (0.3 and -0.7) indicate a moderate positive (negative) linear relationship via a fuzzy-firm linear rule.Values between 0.7 and 1.0 (-0.7 and -1.0) indicate a strong positive (negative) linear relationship via a firm linear rule.The value of r squared is typically taken as "the percent of variation in one variable explained by the other variable," or "the percent of variation shared between the two variables."Linearity Assumption. The correlation coefficient requires that the underlying relationship between the two variables under consideration is linear. If the relationship is known to be linear, or the observed pattern between the two variables appears to be linear, then the correlation coefficient provides a reliable measure of the strength of the linear relationship. If the relationship is known to be nonlinear, or the observed pattern appears to be nonlinear, then the correlation coefficient is not useful, or at least questionable.


When the correlation coefficient is negative?

The dependent variable has an inverse linear relationship with the dependent variable. When the dependent increases, the independent decreases, and conversely.


What does the value of a correlation coefficent reflects?

A correlation reflects the strength of the relationship between two variables. A correlation doesn't reflect causation, but merely that two phenomena are present at the same time. The closer the value is to 1, the stronger the relationship between two variables is. This value can be positive or negative. A negative value merely indicates that, as the values on one variable increase, the values on the second variable decrease. A positive correlation indicates that both values will increase or decrease together.


What does it mean when a positive correlation coefficient between the dependent variable Y and the independent variable X indicates?

It means that the two variables are likely dependent. The higher the number of the positive correlation the stronger the connection.


What does a correlation coefficient represent?

The correlation coefficient for two variables is a measure of the degree to which the variables change together. The correlation coefficient ranges between -1 and +1. At +1, the two variables are in perfect agreement in the sense that any increase in one is matched by an increase in the other. An increase of twice as much in the first is accompanied by double the increase in the second. A correlation coefficient of -1 indicates that the two variables are in perfect opposition. The changes in the two variables are similar to when the correlation coefficient is +1, but this time an increase in one variable is accompanied by a decrease in the other. A correlation coefficient near 0 indicates that the two variables do not move in harmony. An increase in one is as likely to be accompanied by an increase in the other variable as a decrease. It is very very important to remember that a correlation coefficient does not indicate causality.


When the variables in a correlation change simultaneously in the same direction?

When variables in a correlation change simultaneously in the same direction, this indicates a positive correlation. This means that as one variable increases, the other variable also tends to increase. Positive correlations are typically represented by a correlation coefficient that is greater than zero.


What does a correlation coefficient of 1.1 mean?

Well, friend, a correlation coefficient of 1.1 is not possible because correlation coefficients range from -1 to 1. If you meant 1.0, that would indicate a perfect positive linear relationship between two variables. It means as one variable increases, the other variable also increases proportionally.


What is multiple correlation coefficient and partial correlation coefficient?

partial correlation is the relation between two variable after controlling for other variables and multiple correlation is correlation between dependent and group of independent variables.
