What does the y-axis typically represent in a scatter plot?

Back

The y-axis typically represents the dependent variable, which is the variable that is measured or observed.

What does a positive correlation in a scatter plot indicate?

Back

A positive correlation indicates that as one variable increases, the other variable also tends to increase.

What does it mean if a scatter plot shows no correlation?

Back

No correlation means that there is no discernible relationship between the two variables; changes in one variable do not predict changes in the other.

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

Back

The strength of a correlation can be determined by how closely the points cluster around a line of best fit; tighter clustering indicates a stronger correlation.
