Scatter Plot Association

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 association in a scatter plot 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 scatter plot indicate?

Back

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

Front

What is a nonlinear association?

Back

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

Front

What is correlation in the context of scatter plots?

Back

Correlation refers to the strength and direction of a relationship between two variables, which can be positive, negative, or none.

Front

What does a strong positive correlation look like on a scatter plot?

Back

A strong positive correlation is represented by points that are closely clustered around an upward-sloping line.

Front

What does a weak negative correlation look like on a scatter plot?

Back

A weak negative correlation is represented by points that are loosely scattered around a downward-sloping line.

Front

How can you identify no association in a scatter plot?

Back

No association is identified when the points are scattered randomly with no discernible pattern.

Front

What is the significance of outliers in a scatter plot?

Back

Outliers are data points that differ significantly from other observations and can affect the overall correlation.

Front

What type of relationship does a scatter plot with a curve indicate?

Back

A scatter plot with a curve indicates a nonlinear relationship between the variables.
