Scatterplot Association Flashcard

Front

What is a scatterplot?

Back

A scatterplot is a graphical representation of two variables, showing the relationship between them using points on a Cartesian plane.

Front

What does a positive linear association indicate in a scatterplot?

Back

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

Front

What does a negative linear association indicate in a scatterplot?

Back

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

Front

What does 'no association' mean in the context of a scatterplot?

Back

'No association' means that there is no discernible relationship between the two variables being plotted.

Front

What is a non-linear association?

Back

A non-linear association occurs when the relationship between two variables cannot be accurately represented by a straight line.

Front

How can you identify a positive association in a scatterplot?

Back

A positive association can be identified when the points on the scatterplot trend upwards from left to right.

Front

How can you identify a negative association in a scatterplot?

Back

A negative association can be identified when the points on the scatterplot trend downwards from left to right.

Front

What is the significance of outliers in a scatterplot?

Back

Outliers are points that fall far from the general pattern of the data and can significantly affect the interpretation of the association.

Front

What does it mean if a scatterplot shows a cluster of points?

Back

A cluster of points indicates that there is a strong relationship between the variables in that specific range.

Front

What is the purpose of analyzing scatterplots?

Back

Analyzing scatterplots helps to understand the relationship between two quantitative variables and to identify trends, patterns, or correlations.
