Back

It means that changes in one variable do not affect the other variable.

What is a line of best fit?

Back

A line of best fit is a straight line that best represents the data on a scatter plot, showing the general direction of the data points.

Front

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

Back

The strength of a relationship can be determined by how closely the data points cluster around the line of best fit.

Front

What is the purpose of using scatter plots?

Back

Scatter plots are used to visually represent the relationship between two variables and to identify trends or patterns in data.

Front

What does it mean if a scatter plot has a steep slope?

Back

A steep slope indicates a strong relationship between the two variables, meaning that small changes in one variable result in large changes in the other.
