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.
A statistical measure that indicates the extent to which in one factor are accompanied by changes in another is called?
Correlation.
What is correlation coefficient of correlation?
correlation measure the strength of association between to variables.but some times both variables are not in same units.so we cannot measure it with the help of correlation. in this case we use its coefficent which mean unit free. that,s why we use it.
What does it mean if two variables have a negative correlation?
A positive correlation between two variables, say X and Y, means that if one increases, the other will too. No correlation means that they are not related. A negative correlation means that as one increases, the other decreases. Normally you will see this in studies as "Recent studies demonstrated a positive correlation between eating too much and obesity." Or, "recent studies demonstrate a negative correlation between a healthy, balanced diet and obesity".
What does it mean when the correlation coefficient has a positive value?
That as one variable increases so does the other
In a negative correlation as one factor is decreased the other factor?
In a negative correlation as one factor is decreased, the other factor is increased.

Difference between positive and negative corelation?
Positive correlation means that, if something increases, a factor dependent on it also increases. However, if there is negative correlation, the dependent factor decreases.
What does Correlation of plus 1.00 mean?
It mean that there is no correlation between the two variables. The variables are the same.
After a mri of the spine cervical what does clinical correlation mean?
After mri,on lower spine what does clinical correlation mean
What is the correlation coefficient of -0.80 is found between factor A and factor B?
The correlation coefficient is a statistical measure of the extent to which two variables change. A correlation coefficient of -0.80 indicated that, on average, an increase of 1 unit in variable X is accompanied by a decrease of 0.8 units in variable Y. Note that correlation does not imply causation.
What are the properties of correlation?
The correlation coefficient is symmetrical with respect to X and Y i.e.The correlation coefficient is the geometric mean of the two regression coefficients. or .The correlation coefficient lies between -1 and 1. i.e. .

What does the term correlation analysis mean?
Correlation analysis is the relationship of two values. When two items are similar, they will have a high correlation. Should they differ, they will be much lower in variables.
A statistical measure that indicates the extent to which in one factor are accompanied by changes in another is called?
Correlation.
What is the correlation coefficient of -2?
A serious error. The maximum magnitude for a correlation coefficient is 1.The Correlation coefficient is lies between -1 to 1 if it is 0 mean there is no correlation between them. Here they are given less than -1 value so it is not a value of correlation coefficient.
What dose correlation mean?
something that fits together
