It means that there is a general tendency that, if one quantity increases, the other also increases (positive correlation) or decreases (negative correlation). The correlation coefficient is the result of a formula, and tells you how strong the dependency is. For example, a correlation close to zero means that there is no correlation; that any variations in the second variable seem to be random.

What is a line that shows the correlation between two data sets called?
There is no line that shows the correlation between two data sets. The correlation is a variable that ranges between -1 and +1.You may be thinking about regression which, although related, is not the same thing.There is no line that shows the correlation between two data sets.

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 shows the relationships between quantities?
A scatterplot is the best tool. Regression or correlation can often fail to find non-linear relationships.
What is a comparison between two quantities that do not involve time?
A ratio is a comparison of two quantities
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".
The relationship between two quantities that increase or decrease together is called what?
The relationship between two quantities that increase or decrease together is called a positive correlation. This means that as one quantity increases, the other quantity also increases, and vice versa.
What is the type of correlation where there in no relationship between two data sets?
There is no correlation.
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 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.
What does it mean when two variables have a positive correlation?
A positive correlation between two variables means that there is a direct correlation between the variables. As one variable increases, the other variable will also increase.

What is a zero correlation?
a zero correlation means that there is no relationship between the two or more variables.
A relationship between two or more variables that is shown in an observational study is a?

What does Correlation of plus 1.00 mean?
It mean that there is no correlation between the two variables. The variables are the same.
What do you call the relationship between two sets of data?
If the answer you are expecting is correlation, then you are wrong. Correlation refers only to linear relationship between two variables. The correlation for any even relationship over a symmetric domain will be 0. Thus, if y = x2 between the values -a < x < a (for some a), the correlation between y and x will be 0 but few would contend that there is no relationship between the two.
What does correlation mean in maths?

Is the relationship between distance and force in Newton's law of universal gravitation a negative correlation?
Yes, in Newton's law of universal gravitation, the relationship between distance and force is an inverse square relationship. This means that as the distance between two objects increases, the force of gravity between them decreases.
