There were 7 students enrolled in the Introduction to Artificial Intelligence course. These were the student’s scores from the final exam: 64, 70, 80, 80, 90, 98, 100.
What is the mean and mode for the outlined scores?

Answer options

• A. 79.84, 81.40
• B. 80, 83.14
• C. 80, 80
• D. 83.14, 80

Correct answer: D

Explanation

The mean score is calculated by adding all the scores and dividing by the number of students, which results in 83.14. The mode is the score that appears most frequently, which is 80, as it occurs twice. The other options do not correctly represent the calculated mean and mode for the provided scores.
