Scatter Plots

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 does it mean if a scatter plot shows no association?

Back

It means there is no discernible relationship between the two variables; the points are scattered randomly.

Front

How can you identify a linear relationship in a scatter plot?

Back

A linear relationship can be identified if the data points form a straight line or a pattern that closely resembles 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 is the difference between correlation and causation?

Back

Correlation indicates a relationship between two variables, while causation indicates that one variable directly affects the other.

Front

What does it mean if a scatter plot has a strong correlation?

Back

A strong correlation means that the data points are closely clustered around a line, indicating a strong relationship between the variables.

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, patterns, and correlations.

Front

What does it mean if the points in a scatter plot are widely spread out?

Back

Widely spread out points indicate a weak correlation, suggesting that changes in one variable do not consistently relate to changes in the other.
