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 positive Correlation?
Positive correlation is a relationship between two variables in which both variables move in tandem that is in the same direction.
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.
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.
How would you describe a Correlation Coefficient in your own words?
The strength of the relationship between 2 variables. Ex. -.78

What Is a statistic that measures the strength of the relationship between two variables?
correlation
This is the type of research that describes the strength and direction of relationships between variables?
Correlational
How is a linear relationship between two variables measured in statistics?
The Correlation Coefficient computed from the sample data measures the strength and direction of a linear relationship between two variables. The symbol for the sample correlation coefficient is r. The symbol for the population correlation is p (Greek letter rho).
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.
Can the correlation coefficient be represented as a percentage?
No, the correlation coefficient is a measure of the strength and direction of the linear relationship between two variables, and it ranges from -1 to 1. It cannot be represented as a percentage.

What is the best description of an association?
An association is a relationship between two or more variables where they co-occur or change together. It measures the strength and direction of the relationship between variables, indicating how one variable is affected by changes in another. Associations can be positive, negative, or neutral.
What is a measure of strength and direction of the relationship between two variable or data sets?
Correlation
Define correlation coefficients?
Degree and direction of relationship between two or more variables is known as correlation.
