Back

A scatter plot shows a strong correlation if the data points are closely clustered around a straight line.

Front

What does it mean if the points in a scatter plot are widely spread out?

Back

If the points are widely spread out, it indicates a weak correlation between the two variables.

Front

What is the x-axis in a scatter plot?

Back

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

Front

What is the y-axis in a scatter plot?

Back

The y-axis is the vertical axis that typically represents the dependent variable.

Front

How do you interpret the slope of the line in a scatter plot?

Back

The slope indicates the direction and steepness of the relationship between the two variables.
