How can you determine if a line of best fit is accurate?

Back

You can determine if a line of best fit is accurate by checking how closely the data points cluster around the line.

Front

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

Back

No association means that there is no discernible pattern or relationship between the two variables being plotted.

How do you find the coordinates of an outlier?

Back

The coordinates of an outlier are found by identifying the data point that lies farthest from the main cluster of points on the scatter plot.

What is the significance of clusters in data analysis?

Back

Clusters can indicate trends, patterns, or groupings in data that may warrant further investigation.
