ScatterPlots

Front

What is a scatter plot?

Back

A scatter plot is a graph that shows the relationship between two quantitative variables by displaying data points on a two-dimensional axis.

Front

What does a positive correlation in a scatter plot indicate?

Back

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

Front

What does a negative correlation in a scatter plot indicate?

Back

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

Front

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

Back

No correlation means there is no apparent relationship between the two variables; changes in one do not predict changes in the other.

Front

What is a linear association in a scatter plot?

Back

A linear association means the data points can be closely approximated by a straight line.

Front

What is a nonlinear association in a scatter plot?

Back

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

Front

How can you identify a positive linear association in a scatter plot?

Back

A positive linear association is identified by data points that trend upwards from left to right.

Front

How can you identify a negative linear association in a scatter plot?

Back

A negative linear association is identified by data points that trend downwards from left to right.

Front

What does it mean if a scatter plot shows no association?

Back

It means that there is no discernible pattern or relationship between the two variables being plotted.

Front

What is the purpose of using scatter plots?

Back

Scatter plots are used to visually assess the relationship between two variables and to identify trends, correlations, or patterns.
