Let me assume that you are familiar with the (Pearson) correlation coefficient. If you estimate how one variable might be a linear function of another (using least-squares) then the measure of how strong the association is is known as that with which you are correlation coefficient. If you generalise by estimating what linear function one variable is of two or more other variables then the measure of how strong the relationship is is the multiple correlation.
For mathematical reasons which may or may not interest you, and which I won't go into here, if we now go backwards we find that the multiple correlation for the situation where one variable is regressed against one other variable is just the square of the Pearson correlation coefficient.
As you probably know, the Pearson ranges from -1 to +1. Because the multiple correlation is the squared value it ranges only from 0 to 1 and can indicate only degree of association, not the sense of direction.

When a multiple correlation coefficient R123 1 then R213 is?
1
What is the meaning of 0.79 coefficient correlation?
good correlation
What is a correlation where both sets of data values increase or decrease together?
Positive correlation.Positive correlation.Positive correlation.Positive correlation.
What does correlation mean in maths?
Correlation is a statistical measure of the linear association between two variables. It is important to remember that correlation does not mean causation and also that the absence of correlation does not mean the two variables are unrelated.
What does a correlation factor of -0.95 mean?
This means that the correlation is negative but still significant.
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.
How do you explain partial and multiple correlations?
Explain the partial and multiple correlation
How are correlation and causation similar?
both have connections between multiple events
When a multiple correlation coefficient R123 1 then R213 is?
1
What has the author Perry M Ford written?
Perry M. Ford has written: 'Multiple correlation in forecasting seasonal runoff' -- subject(s): Correlation (Statistics), Runoff
Why is possible to relate the temperature of a star to its luminosty or brightness?
By multiple observations it was noted that that correlation was true.
Is there a correlation between Multiple Sclerosis and Anxiety Disorder?
multiple sclerosis may be the body's delayed immune reaction to viruses such as measles, Herpes simplex, rubella, and parainfluenza.
What is the meaning of the word correlation?
Correlation refers to a statistical measure that shows the extent to which two or more variables change together. A positive correlation indicates that the variables move in the same direction, while a negative correlation means they move in opposite directions. Correlation does not imply causation, meaning that just because two variables are correlated does not mean that one causes the other.
Auto correlation and cross correlation?
Auto correlation is the correlation of one signal with itself. Cross correlation is the correlation of one signal with a different signal.
What is the difference between Multicollinearity and Autocorrelation?
The difference between multicollinearity and auto correlation is that multicollinearity is a linear relationship between 2 or more explanatory variables in a multiple regression while while auto-correlation is a type of correlation between values of a process at different points in time, as a function of the two times or of the time difference.
What are three types of correlations?
positive correlation-negative correlation and no correlation
Is 0.5 the strongest correlation coefficient?
No. The strongest correlation coefficient is +1 (positive correlation) and -1 (negative correlation).
