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?

Answer 1

Based on your description of the scatterplot, the correct response would be:

There are no outliers and one cluster.

Here's the reasoning:

• You mentioned a loosely packed cluster of data points between 1 to 4.5 on the horizontal axis and 77 to 98 on the vertical axis, which indicates that there is indeed a cluster.
• You did not mention any individual points that significantly deviate from the pattern of the rest of the data (which would indicate outliers).

Therefore, the characteristics of the graph include one cluster and no outliers.
