CORRELATION

COEFFICIENT

Interpreting correlation using a scatter plot can be subjective. A more precise way to measure the type and strength of a linear

coefficient is given, it is more convenient to use a technology tool to calculate this value.

The range of the correlation coefficient is -1 to 1

CORRELATION AND CAUSATION

1. Is there a direct cause-and-effect relationship between the variables?

2. Is there a reverse cause-and-effect relationship between the variables?

3. Is it possible that the relationship between the variables can be caused by a third variable or perhaps a combination of several other variables?

4. Is it possible that the relationship between two variables may be a coincidence?
