Correlation with Scatter plot

1. If the value of y increases with the value of x, then we can say that the variables have a positive correlation.
2. If the value of y decreases with the value of x, then we can say that the variables have a negative correlation.

How do you read a scatter plot?

You interpret a scatterplot by looking for trends in the data as you go from left to right: If the data show an uphill pattern as you move from left to right, this indicates a positive relationship between X and Y. As the X-values increase (move right), the Y-values tend to increase (move up).
