According to our teacher:
Terms...... In correlation and Regression
Correlation: Is a statistical method used to describe whether a relationship between variables exist.
Regression: A statistical method used to describe the nature of relationship between variables.
Scatter Plot: The graph of the ordered pairs (x,y) of numbers consisting of the independent variable x, and dependent variable y.
Correlation Coefficient: Use to determine the strength of the relationship between two variables.
Types of Relationships
1. Simple relationships- there are only two variables under study.
a. Positive relationship- exist when both variables increase or decrease at the same time.
b. Negative relationship- as one variable increases, the other variable decreases.
2. Multiple relationships- many variables are under study
Independent variable- is the variable in regression that can be controlled or manipulated
Dependent variable- is the variable in regression that cannot be controlled or manipulated
That's all...
