Scatterplots

Front

What is a scatterplot?

Back

A scatterplot is a graph that displays values for typically two variables for a set of data. Each point represents an observation in the dataset.

Front

What does a positive association in a scatterplot indicate?

Back

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

Front

What does a negative association in a scatterplot indicate?

Back

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

Front

What is a line of best fit?

Back

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

Front

What does a weak correlation mean in a scatterplot?

Back

A weak correlation means that the points on the scatterplot are spread out and do not closely follow a clear trend.

Front

What does a strong correlation mean in a scatterplot?

Back

A strong correlation means that the points on the scatterplot are closely clustered around a line, indicating a clear trend.

Front

What is a nonlinear association?

Back

A nonlinear association occurs when the relationship between the variables cannot be accurately represented by a straight line.

Front

How can you identify a negative linear association in a scatterplot?

Back

A negative linear association can be identified when the points slope downwards from left to right.

Front

How can you identify a positive linear association in a scatterplot?

Back

A positive linear association can be identified when the points slope upwards from left to right.

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.
