Positive Correlation
If the pattern of points on a scatter diagram shows a linear path diagonally across the graph paper from the bottom left-hand corner to the top right, it indicates a positive correlation between the variables being plotted.

Definition of Positive Correlation
Positive correlation is a statistical relationship between two variables in which they both move in the same direction. When one variable increases, the other variable also tends to increase. Similarly, when one variable decreases, the other variable also tends to decrease.

Explanation
When the scatter diagram shows a linear path from the bottom left-hand corner to the top right, it suggests a positive correlation between the variables. This means that as one variable increases, the other variable also tends to increase.

Visual Representation
Visually, a scatter plot with a positive correlation would show points that form a diagonal line from the bottom left to the top right of the graph paper. The points would be clustered around this line, indicating a strong positive relationship between the variables.

Example
For example, let's consider a scatter plot of the number of hours studied and the exam scores of a group of students. If the scatter plot shows a linear path from the bottom left to the top right, it suggests that as the number of hours studied increases, the exam scores also tend to increase. This indicates a positive correlation between the two variables.

Interpretation
In this case, a positive correlation between the number of hours studied and exam scores implies that studying more hours is associated with higher exam scores. This pattern suggests that there is a direct relationship between the two variables, and studying more has a positive impact on exam performance.

Conclusion
In summary, if the pattern of points on a scatter diagram shows a linear path diagonally across the graph paper from the bottom left-hand corner to the top right, it indicates a positive correlation between the variables being plotted. This means that as one variable increases, the other variable also tends to increase.
