vitfil [10]

Answer:

<u>Middleton only</u>

Step-by-step explanation:

Sometimes, in a data set, there is a number that is much larger or much smaller than the others generally tend to be. These numbers that are far away from the average are known as outliers

The data set for the students at Middleton Middle School:

1 2 2 2 2 3 3 3 3 3 4 4 4 4 5 5 5 5 6 9

We can note that most of data is between 1 and 6, the gap between them is 0 or 1, but there is one of the data which is 9, the gap between 9 and 6 is 3

<u>So, 9 would be considered an outlier.</u>

<u>So, The shapes of plots shows an outlier is Middleton only</u>

The data set for the students at Westwood Middle School:

2 2 2 2 3 3 3 3 3 4 4 4 4 5 5 5 5 6 6 6

We can note that all of data is between 2 and 6, the gap between them is 0 or 1

<u>So, There is no outlier for the set of data.</u>
