Interpret Bivariate Data Practice

Front

What is bivariate data?

Back

Bivariate data involves two variables and is used to determine the relationship between them.

Front

What does a negative association between two variables indicate?

Back

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

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.

Front

What does a positive association between two variables indicate?

Back

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

Front

What is correlation?

Back

Correlation is a statistical measure that describes the extent to which two variables change together.

Front

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

Back

No association means that there is no discernible relationship between the two variables; changes in one do not predict changes in the other.

Front

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

Back

A negative correlation is identified when the data points slope downwards from left to right.

Front

What is a linear relationship?

Back

A linear relationship is a relationship between two variables that can be represented by a straight line on a graph.

Front

What is a non-linear relationship?

Back

A non-linear relationship is a relationship between two variables that does not follow a straight line when graphed.

Front

What does it mean if a scatter plot is linear and positive?

Back

It means that as one variable increases, the other variable also increases, and the relationship can be represented by a straight line.
