Types of correlations
Positive correlation
Negative correlation
Curvilinear correlation
Zero correlation
Correlations
An analysis of the relationship between co variables
Strengths
Correlations allow researchers to investigate situations that could not be done experimentally .
Limitations
Collations cannot reliably establish cause and effect
Positive correlation
When one variable increases the other variable increases
Negative correlation
When one variable increases the other variable Decreases
Curvilinear correlation
Where is there is both a positive and negative relationship between two variables
Zero correlation
Where there is no clear relationship between variables
