Front

What is an outlier in a scatterplot?

Back

An outlier is a point that is far outside the main cluster of points/ordered pairs.

Front

What does a positive correlation in a scatterplot indicate?

Back

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

Front

What does a negative correlation in a scatterplot indicate?

Back

A negative correlation indicates that as one variable increases, the other variable decreases.

Front

What is the line of best fit?

Back

The line of best fit is a straight line that best represents the data on a scatterplot, showing the overall trend.

Front

How can you describe a scatterplot with no correlation?

Back

A scatterplot with no correlation shows no apparent relationship between the two variables.

Front

What does it mean if the line of best fit slopes upwards?

Back

If the line of best fit slopes upwards, it indicates a positive correlation between the variables.

Front

What does it mean if the line of best fit slopes downwards?

Back

If the line of best fit slopes downwards, it indicates a negative correlation between the variables.

Front

How can you predict a value using a scatterplot?

Back

You can predict a value by finding the corresponding point on the line of best fit for a given input.

Front

What is bivariate data?

Back

Bivariate data involves two different variables and their relationship.

Front

What is a scatterplot?

Back

A scatterplot is a graph that displays values for two variables for a set of data.
