Question
Use the image to answer the question.
A scatterplot shows the number of hours studied versus test grade.
The horizontal axis shows the number of hours studied, ranging from 0 to 10 in increments of 1. The vertical axis shows the test grade, ranging from 0 to 100 in increments of 5, starting with a jump from 0 to 35. A kink is shown on the vertical axis close to origin. A dot is plotted at 0.5 on the horizontal axis and 45 on the vertical axis. A loosely packed cluster of data plots is plotted between 1 to 4.5 on the horizontal axis and 77 and 98 on the vertical axis.
What are the characteristics of the graph?

Based on your description of the scatterplot, it sounds like there is a loosely packed cluster of data points between 1 to 4.5 hours studied and 77 to 98 test grades. Additionally, there is a point at 0.5 hours studied and 45 test grade, which could be considered an outlier since it is notably separate from the main cluster.
Given this analysis, the most accurate response would be:
There is one cluster and one outlier.
