Scatterplot- a relational chart that displays the X,Y coordinates on a grid. The correlation of the point helps to determine a trend in the data.
Here hours of study and test scores are plotted on a graph, with each point representing one person or test. Each point is charted independently on the graph, from which a conclusion can be drawn. Because the point show a positive relationship between more hours of study and higher test scores, it can be assumed that studying more will positively affect the test score. If the points were more randomly distributed, it would be harder to come to a conclusion, or the conclusion might be that more hours of study does not affect the test score.
