Answer :
The correct answer is c. diagonal line, which indicates that in a scatter diagram (or scatterplot), the closer the data points are to a diagonal line, the stronger the correlation between the two variables is.
In the context of a scatter diagram, the closer data points are to a diagonal line, the more closely the two variables are related. The correct answer to the question is c. diagonal line. A scatter diagram, or scatterplot, is used to show the relationship between two variables. When points on a scatterplot form a pattern that is close to a straight line, it indicates a strong correlation between the variables. If the points are widely scattered and do not approximate a line, this suggests a weaker correlation. If points are clustered close to a line that goes from the lower left to the upper right, it indicates a positive relationship, meaning that as one variable increases, the other variable also increases. Conversely, if the points are close to a line that goes from the upper left to the lower right, it represents a negative relationship, where one variable increases as the other decreases. The correct option is c.
