Scatter Plot Association

Front

What is a scatter plot?

Back

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

Front

What does a strong positive linear association indicate?

Back

A strong positive linear association indicates that as one variable increases, the other variable also increases in a consistent manner.

Front

What does a strong negative linear association indicate?

Back

A strong negative linear association indicates that as one variable increases, the other variable decreases in a consistent manner.

Front

What is no association in a scatter plot?

Back

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

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 strong association in a scatter plot?

Back

A strong association is identified by data points that are closely clustered around a line, indicating a clear relationship between the variables.

Front

What does it mean if a scatter plot shows a weak association?

Back

A weak association means that the data points are spread out and do not closely follow a clear trend or pattern.

Front

What is the purpose of using scatter plots?

Back

Scatter plots are used to visually represent the relationship between two variables, making it easier to identify trends, correlations, and outliers.

Front

What is correlation?

Back

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

Front

What is the difference between positive and negative correlation?

Back

Positive correlation means that both variables increase or decrease together, while negative correlation means that one variable increases as the other decreases.
