A scatter plot is a graphical representation that shows the relationship between two quantitative datasets. Each point on the scatter plot represents an ordered pair of values from the two datasets1. When analyzing scatter plots, one important aspect to consider is the correlation between the datasets, which indicates the strength and direction of their relationship.
Identifying Strong Negative Correlation
A strong negative correlation occurs when the values of one dataset decrease as the values of the other dataset increase. In a scatter plot, this is visualized by points that cluster closely around a downward-sloping line1. The closer the points are to this line, the stronger the negative correlation.
Example of Strong Negative Correlation
Consider the following example:
Explanatory Variable (X): Number of hours studied per week
Response Variable (Y): Number of errors made on a test
