Question
The scatter plot shows the relationship between the amount of time students in a mathematics class studied for an exam and their score on the exam.
scatter plot titled mathematics class, with the x axis labeled time studying in minutes and the y axis labeled score on exam with points at 0 comma 30, 10 comma 35, 30 comma 40, 40 comma 47, 50 comma 50, 60 comma 56, 70 comma 60, 75 comma 65, 80 comma 70, 85 comma 78, 90 comma 83, 95 comma 90, 100 comma 95, and 105 comma 100
Which of the following describes the pattern of association for the graph?
There is a positive linear association.
There is a positive nonlinear association.
There is a negative linear association.
There is a negative nonlinear association.

To determine the pattern of association described by the scatter plot, we can analyze the distribution of the points based on the relationship between time studied (on the x-axis) and scores on the exam (on the y-axis).
From the provided coordinates of the points, we see that as the time studied increases, the exam scores also tend to increase. This indicates a positive relationship.
Moreover, the points tend to cluster around a linear trend rather than displaying a clear curve or nonlinear pattern. Although there may be slight fluctuations in scores at higher study times, the overall trend shows a general increase in scores with increased study time.
Therefore, the best description of the pattern of association for the graph is:
**There is a positive linear association.**
