When r = 1, all the points in a scatter diagramwould lie:a)On a straig...
Explanation:
When r = 1, it means there is a perfect positive correlation between the two variables. This implies that all the points in the scatter diagram would lie on a straight line.
Reasons:
There are two reasons why all points in a scatter diagram would lie on a straight line when r = 1:
1. Perfect Positive Correlation:
When r = 1, it indicates a perfect positive correlation between the two variables. This means that as one variable increases, the other variable also increases proportionally. Therefore, when we plot the data on a scatter diagram, all the points would be aligned on a straight line.
2. Linear Relationship:
Another reason why all points in a scatter diagram would lie on a straight line when r = 1 is that there is a linear relationship between the two variables. This means that the relationship between the two variables can be expressed mathematically by a straight line equation. Therefore, when we plot the data on a scatter diagram, all the points would be aligned on a straight line.
Conclusion:
In conclusion, when r = 1, all the points in a scatter diagram would lie on a straight line directed from lower left to upper right. This is because there is a perfect positive correlation between the two variables, and there is a linear relationship between them.
