Front

What does a positive correlation indicate in a scatterplot?

Back

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

Front

What does a negative correlation indicate in a scatterplot?

Back

A negative correlation indicates that as one variable increases, the other variable tends to decrease.

Front

What is the purpose of a trendline in a scatterplot?

Back

A trendline is used to show the general direction or pattern of the data points in a scatterplot.

Front

How can you determine the strength of a correlation from a scatterplot?

Back

The strength of a correlation can be determined by how closely the data points cluster around the trendline; tighter clusters indicate stronger correlations.

Front

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

Back

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

Front

What is the x-axis typically used for in a scatterplot?

Back

The x-axis is typically used to represent the independent variable.

Front

What is the y-axis typically used for in a scatterplot?

Back

The y-axis is typically used to represent the dependent variable.

Front

What type of correlation is indicated by a scatterplot that slopes upwards?

Back

A scatterplot that slopes upwards indicates a positive correlation.

Front

What type of correlation is indicated by a scatterplot that slopes downwards?

Back

A scatterplot that slopes downwards indicates a negative correlation.
