How can you determine the strength of a correlation in a scatter plot?

Back

By observing how closely the data points cluster around the Line of Best Fit; tighter clusters indicate stronger correlations.

Front

What is a weak correlation?

Back

A relationship between two variables where the data points are widely scattered around the Line of Best Fit.

Front

What is a strong correlation?

Back

A relationship where the data points are closely clustered around the Line of Best Fit.

Front

How do you rank scatter plots according to correlation strength?

Back

By comparing how closely the data points cluster around their respective Lines of Best Fit.

Front

What is the purpose of the Line of Best Fit in data analysis?

Back

To summarize the relationship between two variables and make predictions based on that relationship.

Front

What does it mean if a scatter plot shows 'none' association?

Back
