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 correlation in a scatter plot indicate?

Back

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

Front

What does a negative correlation in a scatter plot indicate?

Back

A negative correlation indicates that as one variable increases, the other variable decreases.

Front

What is a linear relationship in a scatter plot?

Back

A linear relationship is when the data points in a scatter plot can be approximated by a straight line.

Front

What is a non-linear relationship in a scatter plot?

Back

A non-linear relationship is when the data points do not follow a straight line and may curve or cluster in a different pattern.

Front

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

Back

A strong correlation is indicated by data points that are closely clustered around a straight line.

Front

What does it mean if a scatter plot has no correlation?

Back

No correlation means there is no discernible relationship between the two variables, and the data points are scattered randomly.

Front

What is the purpose of using scatter plots?

Back

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

Front

What does the slope of a line in a scatter plot represent?

Back

The slope represents the rate of change between the two variables; a positive slope indicates a positive correlation, while a negative slope indicates a negative correlation.

Front

What is the difference between strong and weak correlation?

Back

Strong correlation means the data points are closely aligned with a line, while weak correlation means the data points are more spread out.
