The relationship between two variables is called a relation. A relation in which a set of input values maps onto a set of output values such that each input corresponds to at most one output is called a "function." Functions do not necessarily have to be lines; they do not even have to be exponential, or parabolic, or continuous. A bunch of scattered points or lines that meets the requirements can still be considered a function involving two variables.

What is The measure of the relationship between two variables?
correlation * * * * * Only if the relationship is linear. For example, the correlataion between y and x when y = x2 is zero. But a very strong relationship between the two variables.
What is the statistical measure of a relationship between two variables?
corrrelation
What is positive Correlation?
Positive correlation is a relationship between two variables in which both variables move in tandem that is in the same direction.
The degree of relationship between two variables is of particular concern in which type of study?
Explanatory
Which of these provides relationship between two variables and provides a visual correlation coefficient?
Trendline
Used to show the relationship between two variables?
Line graph is used to show relationship between two variables.
If coefficient of correlation r between two variables is zero does it mean that there is no relationship between the variables Justify your answer?
"If coefficient of correlation, "r" between two variables is zero, does it mean that there is no relationship between the variables? Justify your answer".
Why was there a need to invent linear equation in two variables?
If two variables are related, then the simplest relationship between them is a linear one. The linear equation expresses such a relationship.If two variables are related, then the simplest relationship between them is a linear one.

What is the relationship between two variables if the product of the variables is constant?
Inversely proportional.
What is the statistical measure of a relationship between two variables?
corrrelation
Strongest relationship between two variables?
Equality (identity).
What is the relationship between two variables also known as?
A correlation
How does finding slope compare to finding the rate of change between two variables in a linear relationship?
The slope of a line is the same thing as the rate of change between two variables in a linear relationship.
How do you tell whether the relationship between two variables is linear?
By definition, if you graph the relationship between two variables and the result is a straight line (of whatever slope) that is a linear relationship. If it is a curve, rather than a straight line, then it is not linear.
Is helpful in determining whether there is a relationship between two variables?
it depends on who you are
What is the tool used to show the relationship between two variables?
A function.
