Back

A cluster is a group of data points that are located close together in a certain area of the graph.

Front

What is a gap in a scatter plot?

Back

A gap is an area in the scatter plot where there are no data points, indicating a lack of observations in that range.

Front

How can you use a trend line to make predictions?

Back

You can use a trend line to estimate the value of one variable based on the value of another variable by finding where the value intersects the line.

Front

What does it mean if a scatter plot has a peak?

Back

A peak indicates a concentration of data points at a certain value, suggesting that many observations share that value.

What is the purpose of analyzing scatter plots?

Back

Analyzing scatter plots helps to identify relationships, trends, and patterns between two variables.
