What a correlation of 0.30 means that the independent variable explains -- percent of the variance in the dependent variable?

The independent variable explains .32*100 percent of the variance in the dependent variable.
This is 9%.
The explainable variance is always the square of the correlation (r).

Is a decrease in the independent variable and a decrease in the dependent variable a positive correlation?
yes
What serves as a standard of comparison to evaluate the effectof the independent variableon the dependent variable?
In statistics, the standard of comparison is the r2 which is a percentage that explains what percentage of the dependent variable can be accounted for by the independent variable.
What is a perfect correlation?
If all variations in the dependent variable can be fully explained by the independent variables - so that there is no residual "error" - the correlation is said to be perfect.
Which variable is independent and which variable is dependent?
and independent variable is bigger than a dependent variable
What are the advantages of regression over correlation?
Correlation is a measure of association between two variables and the variables are not designated as dependent or independent. Simple regression is used to examine the relationship between one dependent and one independent variable. It goes beyond correlation by adding prediction capabilities.
Positive correlation implies what--dependent variable improves as independent variable increases or dependent variable decreases as independent variable increases or?
dependent variable improves (or increases) as independent variable increases
Is a decrease in the independent variable and a decrease in the dependent variable a positive correlation?
yes
What is mediator in experiments?
The mediator variable explains the relationship between the independent variable and the dependent variable.
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 serves as a standard of comparison to evaluate the effectof the independent variableon the dependent variable?
In statistics, the standard of comparison is the r2 which is a percentage that explains what percentage of the dependent variable can be accounted for by the independent variable.
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 is a perfect correlation?
If all variations in the dependent variable can be fully explained by the independent variables - so that there is no residual "error" - the correlation is said to be perfect.
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.
What is independent a dependent variables?
The independent variable is the variable that is altered by the scientist, and the dependent variable's value is dependent on the value of the independent variable.
What are the advantages of regression over correlation?
Correlation is a measure of association between two variables and the variables are not designated as dependent or independent. Simple regression is used to examine the relationship between one dependent and one independent variable. It goes beyond correlation by adding prediction capabilities.
What causes change in a dependent variable?
The dependent variable is dependent on the independent variable, so when the independent variable changes, so does the dependent variable.
Which variable is independent and which variable is dependent?
and independent variable is bigger than a dependent variable
