Correlation between two variables implies a linear relationship between them.
The existence of correlation implies no causal relationship: the two could be causally related to a third variable. For example, my age is correlated with the number of TV sets in the UK but obviously there is no causal link between them - they are both linked to time.

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.
What is a relationship between two variables in which one variable increases as the other decreases?
This is called an "inverse" relationship.
What is a good way to show the relationship between two variables?
line graph
What trend line means?
The trend line for a scatter plot is a line that best captures the nature of the relationship between two variables. It may or may not be straight. The trend line for a scatter plot is a line that best captures the nature of the relationship between two variables. It may or may not be straight.

What does ''highly correlated'' mean?
Correlation is defined as the degree of relationship between two or more variables. It is also called the simple correlation. The degree of relationship between two or more variables is called multi correlation. when two or more variables are said to be higjly correlated it means that they have a strong relationship such that a given rise or fall in one variable will lead to a direct change in the other variable or variables. good examples of highly correlated variables are price and quantity, wage rate and out put, tax and income.
Can a correlated study determine when there is lack of a relationship between two variables?
Sure. If you can observe that when variable A changed, variable B didn't change, and this happens repeatedly, that is a good indication that there is no relationship between those variables.
If two variables are highly correlated the correlation coefficient will be at or near zero-true or false?
If two variables are highly correlated, the Pearson correlation will be close to -1.0 or +1.0. A correlation of zero shows no relationship.
What is correlational survey?
Correlational surveys involve measuring the relationship between two or more variables without manipulating them. By collecting data on these variables from a sample of participants, researchers can determine the extent to which changes in one variable are associated with changes in another, providing insight into potential patterns or connections between the variables.
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".
Two variables that are likely to be correlated?
Height and Weight.
Do two variables that are significantly correlated share a variance?
No, they do not.
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.

The straight line on the graph tells us about the relationship between two temperatures?
A straight line on a graph usually indicates a linear relationship between two variables, in this case, two temperatures. The slope of the line can tell us the rate of change between the two temperatures. If the line has a positive slope, it means the temperatures are positively correlated, while a negative slope indicates a negative correlation.
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 relationship between two variables if the product of the variables is constant?
Inversely proportional.
