A scatterplot shows the number of hours studied versus test grade.

Question

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?

There is one cluster and one outlier.

There are no clusters.

Answer 1

Based on the description of the scatterplot, the characteristics are as follows:

1. One cluster: The loosely packed cluster of data points between 1 to 4.5 hours on the horizontal axis and test grades between 77 and 98 on the vertical axis indicates a significant grouping of points in that range.

2. No outliers: The dot plotted at 0.5 hours and 45 on the vertical axis does not seem to be far removed from the main cluster, and given that it fits within the trend of the data, it is likely not an outlier.

Therefore, the most accurate response based on the provided options is:

There are no outliers and one cluster.
