The kind of relationship between class study time and test scores is shown on the scatter plot is Positive correlation.
No correlation: The points on the scatter plot would be scattered randomly, without any discernible pattern or relationship between the two variables.
Positive correlation: The points on the scatter plot would be concentrated in the upper-right or lower-left quadrant, indicating that as one variable increases, the other variable also increases.
Negative correlation: The points on the scatter plot would be concentrated in the upper-left or lower-right quadrant, indicating that as one variable increases, the other variable decreases.
Positive then negative correlation: The points on the scatter plot would start in one quadrant and then switch to the opposite quadrant, indicating that the relationship between the two variables is initially positive and then becomes negative.
