No relationship
What does the Partial Correlation measure?
Relationship without considering other independent variables
What is necessary to calculate the correlation coefficient?
Scatter diagram
Who first derived the Pearson Product-Moment Correlation Coefficient?
Karl Pearson
What is the definition of simple correlation?
The relationship between two variables involving constant rate of change
What type of correlation involves a change in one variable that is not at a fixed rate?
Curvilinear correlation
What is the characteristic of inverse correlation?
For every increase in one variable, there is a corresponding decrease in the second variable
Which type of correlation involves more than two variables?
Non-linear correlation
What defines multiple correlation?
The relationship between a dependent variable and more than two independent variables
For every increase in one variable, there is a corresponding decrease in the second variable is an example of ______ correlation.
inverse
What characterizes joint correlation?
The relationship between a dependent variable and two or more independent variables is changed with the addition of another independent variable
Linear correlation means that a change in one variable is at a constant rate with respect to the change in the second variable. The correlation between the variables may either be showing direct or ______ relationship.
inverse
Curvilinear correlation means that a change in one variable is not at a fixed rate. It may be increasing or decreasing with respect to the change in the other variable, which means the relationship is not ______.
linear
Multiple correlations involve more than two variables. The relationship between a dependent variable and two or more independent variables is usually measured. ______ correlation involves more than two variables.
Non-linear
Joint correlation is the correlation between the dependent variable and two or more variables, and it is changed with the addition of another independent variable. This defines ______ correlation.
Joint
The relationship in ______ correlation is similar to curvilinear correlation, however in this correlation more than two variables are involved.
non-linear
The values of the coefficient of correlation ranges between +1 to ______. Zero represents no relationship.
-1
The Pearson Product-Moment Correlation Coefficient is commonly called the Pearson ______
r

correlation
The Partial Correlation is a relative measure of relationship between the dependent variable and a particular independent variable, without considering the effect of the other independent ______ under study.
variables
