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 the statistical measure of a relationship between two variables?
corrrelation
What is the difference between correlation analysis and?
Correlation analysis is a type of statistical analysis used to measure the strength of the relationship between two variables. It is used to determine whether there is a cause-and-effect relationship between two variables or if one of the variables is simply related to the other. It is usually expressed as a correlation coefficient a number between -1 and 1. A positive correlation coefficient means that the variables move in the same direction while a negative correlation coefficient means they move in opposite directions.Regression analysis is a type of statistical analysis used to predict the value of one variable based on the value of another. This type of analysis is used to determine the relationship between two or more variables and to determine the direction strength and form of the relationship. Regression analysis is useful for predicting future values of the dependent variable given a set of independent variables.Correlation Analysis is used to measure the strength of the relationship between two variables.Regression Analysis is used to predict the value of one variable based on the value of another.
What measures the strength of the linear relationship between two quantitative variables?
The coefficient of determination, otherwise known as the r^2 value, measures the strength of the linear relationship between two quantitative variables. An r^2 value of 1 indicates a complete linear relationship while a value of 0 means there is no relationship.
How would you describe a Correlation Coefficient in your own words?
The strength of the relationship between 2 variables. Ex. -.78

What is Co-relational statistical procedure?
A Co-relational statistical procedure is a technique used to know the relationship between two variables or measures the closeness of two statistical data. A statistical graph is the best representation of it.

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.
How would you describe a Correlation Coefficient in your own words?
The strength of the relationship between 2 variables. Ex. -.78
What is co relational research?
Correlational research is a type of non-experimental research design that examines the relationship between two or more variables without manipulating them. It seeks to determine if there is a statistical relationship between the variables, but does not imply causation. Correlational studies provide information about how variables are related and can help generate hypotheses for further research.
What is regression analysis?
In statistics, regression analysis is a statistical process for estimating the relationships among variables. It includes many techniques for modeling and analyzing several variables, when the focus is on the relationship between a dependent variable and one or more independent variables.
What are the relations between the different variables?
There are no relations between different variables. If you want to enable a relationship between variables, you must write the code to implement that relationship. Encapsulating the variables within a class is the most obvious way of defining a relationship between variables.
Would the absence of independent variable imply a cause and effect relationship between 2 variables?
No, it would not. It is possible that the statistical model is under-specified and that the variables being studied are all "caused" by another variable.
