How can you predict values using a scatterplot?

Back

You can predict values by finding the trend in the scatterplot and estimating the value based on the observed data points.

What is a linear relationship in a scatterplot?

Back

A linear relationship is when the data points in a scatterplot form a straight line, indicating a consistent rate of change between the two variables.

How do you identify outliers in a scatterplot?

Back

Outliers are points that fall far away from the general cluster of data points in a scatterplot, indicating they do not fit the overall trend.

What is the x-axis in a scatterplot?

Back

The x-axis is the horizontal axis that typically represents the independent variable in a scatterplot.
