Question

which scatterplots display an example of a cluster? check all that apply.

Explanation:

Define a cluster in a scatterplot

A cluster is a distinct group of data points that are gathered closely together in a specific region of the graph, showing a high density compared to other areas.

Analyze each scatterplot

• First scatterplot (left): The data points are tightly grouped together in a single, dense region. This represents a clear cluster.
• Second scatterplot (middle): The data points are widely scattered and spread out across the entire grid with no dense grouping. This does not show a cluster.
• Third scatterplot (right): The data points are tightly grouped together in a single, dense region forming a downward trend. This represents a clear cluster.

Answer:

• (A) The first scatterplot (left) (Correct answer)
• (B) The second scatterplot (middle)
• (C) The third scatterplot (right) (Correct answer)
