Math Problem Statement

Based on this scatterplot, approximately what score should a student with 6 absences expect to receive on the final exam?

Solution

To determine the approximate score a student with 6 absences should expect based on the scatterplot:

  1. Locate 6 absences on the x-axis.
  2. Move vertically to identify the cluster of points corresponding to 6 absences.
  3. Observe the approximate range of exam scores.

From the scatterplot:

  • At 6 absences, the points appear to align around the 70–75 range.
  • Therefore, the expected score is approximately 76.

The correct answer is D. 76.


Would you like further clarification or a breakdown of how scatterplots work?

Here are 5 related questions you might find helpful:

  1. What is the general trend between absences and exam scores in this scatterplot?
  2. How can you estimate values using scatterplots with no exact data points?
  3. How would the line of best fit help in predicting scores for other absence values?
  4. How do outliers affect scatterplots and their interpretations?
  5. What other variables might explain the changes in exam scores?

Tip: In scatterplots, a negative correlation means that as one variable increases (like absences), the other tends to decrease (like exam scores).
