Question

match the correct letter with the corresponding linear feature.
a
b
c
d
positive association
cluster
outlier
negative association

Explanation:

• Positive Association: In a positive association, as one variable increases, the other variable also tends to increase. In plot A, as the \(x -\)values increase, the \(y -\)values generally increase.
• Cluster: A cluster is a group of data points that are close together. In plot B, there are two distinct groups of data points.
• Negative Association: In a negative association, as one variable increases, the other variable tends to decrease. In plot C, as the \(x -\)values increase, the \(y -\)values generally decrease.
• Outlier: An outlier is a data point that is far from the other data points. In plot D, the data points are more spread out compared to the clustering in B, but the key is that there is no clear positive or negative trend like in A and C.

Answer:

A. Positive Association
B. Cluster
C. Negative Association
D. Outlier
