Answer:
(6, 97) is the outlier.
Step-by-step explanation:
When we have a data set:
x: x₁, x₂, x₃, ..., xₙ
y: y₁, y₂, y₃, ..., yₙ
Each one of the pairs (x₁, y₁), (x₂, y₂), etc, is an ordered pair that belongs to the data set.
Usually, these values are distributed in some way that, we assume, is normalized. So if one of these ordered pairs is really different from the others, then that pair is called an "outlier".
In the data set, we have:
Number of homework completed vs Score assigned.
You can see that, as the number of homework completed increases, also does the score
For example, for the smaller number of homework completed, (5) the score is 67, the minimum score.
And as the number of homework completed reaches to 10, the score increases to 90 or 98.
But there is an outlier there, you can see that a student that only completed 6 times the homework, has a score of 97 (one of the largest scores) (this score is more than all the scores for the students with 6, 7, 8 and 9 completed homeworks) so we can conclude that this one is the outlier.
(6, 97) is the outlier.
