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, here are the characteristics identified:

  • The dot at 0.5 hours studied and 45 test grade could potentially be an outlier since it's somewhat isolated and significantly lower than the cluster of data points at higher hours studied (between 1 to 4.5 hours).
  • The cluster observed is formed by the data points between 1 to 4.5 hours studied and test grades ranging from 77 to 98.

Therefore, the best response would be: There is one cluster and one outlier.
