Back

If data points are closely grouped, it is considered a cluster, indicating a strong relationship between the variables.

Front

How can you identify a linear relationship in a scatter plot?

Back

A linear relationship can be identified if the data points form a straight line or a pattern that resembles a straight line.

Front

What does it mean if there is no correlation in a scatter plot?

Back

No correlation means that there is no apparent relationship between the two variables; the data points are scattered randomly.

Front

What is the purpose of a scatter plot?

Back

The purpose of a scatter plot is to visually display the relationship between two quantitative variables.

Front

What does it mean if a scatter plot has one outlier?

Back

It means that there is one data point that does not fit the overall pattern of the other data points.

Front

What is the significance of the slope in a scatter plot?

Back
