Scatter Plots and Line of Best Fit

Front

What is a scatter plot?

Back

A scatter plot is a graph that shows the relationship between two data sets.

Front

What does a positive linear association in a scatter plot indicate?

Back

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

Front

What does a negative linear association in a scatter plot indicate?

Back

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

Front

What does 'no association' mean in a scatter plot?

Back

No association means that there is no predictable pattern between the two variables.

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 scatter plot.

Front

How can you identify a positive correlation in a scatter plot?

Back

A positive correlation is identified when the points on the scatter plot slope upwards from left to right.

Front

How can you identify a negative correlation in a scatter plot?

Back

A negative correlation is identified when the points on the scatter plot slope downwards from left to right.

Front

What does a scatter plot with no correlation look like?

Back

A scatter plot with no correlation shows points that are randomly scattered without any clear pattern.

Front

What is the purpose of using a scatter plot?

Back

The purpose of using a scatter plot is to visually display the relationship between two quantitative variables.

Front

What type of data is best represented in a scatter plot?

Back

Quantitative data is best represented in a scatter plot.
