What is the statistical measure of a relationship between two variables?
corrrelation
What do you call a measure of the strength and direction of the relationship between two variables or data sets?
A measure of association. You might be thinking of the correlation coefficient in particular.
What does correlation tell us?
Correlation is a statistical technique that is used to measure and describe the strength and direction of the relationship between two variables.
A relationship between two variables or sets of data is called what?
Some people will give the answer "correlation". But that is not correct for the following reason: Consider the coordinates of a circle. There is obviously a very strong relationship between the x coordinate and the y coordinate. The correlation between the two is not just small, but 0. The correlation between two variables is a measure of the linear relationship between them. But there can be non-linear relationships which will not necessarily be reflected by any correlation.

How are rates and unit rates similar?
They both measure a linear relationship between two variables.
Is the coefficient of correlation a useful measure of the linear relationship between two variables true or false?
True
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".
What do line plots measure?
Usually all they do is show the values of two continuous variables for a set of values. There may or may not be a relationship between the two variables. If there is, it may or may not be a causal relationship. It does not have to be a linear relationship or even a relationship that maintains its characteristic.
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 cor-relational research?
Correlation Research Method, a statistical measure of a relationship between two or more variables, gives an indication of how one variable may predict another.
What is the relationship between two variables if the product of the variables is constant?
Inversely proportional.
What does correlation tell us?
Correlation is a statistical technique that is used to measure and describe the strength and direction of the relationship between two variables.
What is numerical measure of linear association between two variables?
The numerical measure of linear association between two variables is typically represented by the Pearson correlation coefficient (r). This value ranges from -1 to 1, where -1 indicates a perfect negative linear relationship, 1 indicates a perfect positive linear relationship, and 0 signifies no linear relationship. The closer the coefficient is to either -1 or 1, the stronger the linear association between the variables.
