Question

use the data in the scatter plot below to answer each of the questions.
a college professor made a scatter plot showing the number of absences several students had compared to their grade on the final exam.
a which best describes the type of association between the number of absences and the final exam grade?
positive negative none
b as the number of absences increases, describe what happens to the final exam grade:
as the number of absences decreases, describe what happens to the final exam grade:
c are there any outliers on the scatter plot?
if so, use the shape tool to create a circle around the data point(s).

Explanation:

Part A

Step1: Analyze scatter plot trend

In a scatter plot, a negative association means as one variable increases, the other decreases. Here, as absences (x - axis) increase, final exam grade (y - axis) decreases. So the association is negative.

Step1: Observe the relationship

From the scatter plot, when the number of absences (x - value) increases, the final exam grade (y - value) shows a downward trend. When absences decrease, the grade shows an upward trend.

Step2: Describe the trends

As absences increase, the final exam grade decreases. As absences decrease, the final exam grade increases.

Step1: Identify outliers

An outlier is a data point that is far from the general cluster. Looking at the scatter plot, the point with 1 absence and grade around 55 (or the point that is far from the main group of points) is an outlier. Also, the point with 7 absences and grade around 95 is an outlier as it's far from the general negative trend cluster. (Visually, we can circle these points. For example, the point at (1, 55) and (7, 95) are outliers.)

Answer:

negative
