Scatter Plot and Associations

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 linear relationship in a scatter plot?

Back

A linear relationship is when the data points in a scatter plot form a straight line, indicating a consistent rate of change between the variables.

Front

What is a nonlinear relationship in a scatter plot?

Back

A nonlinear relationship is when the data points do not form a straight line, indicating that the rate of change between the variables varies.

Front

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

Back

If a scatter plot shows no relationship, it means that there is no discernible pattern or correlation between the two variables.

Front

What are the axes in a scatter plot typically labeled with?

Back

The horizontal axis (x-axis) is usually labeled with the independent variable, while the vertical axis (y-axis) is labeled with the dependent variable.

Front

How can you determine the strength of an association in a scatter plot?

Back

The strength of an association can be determined by how closely the data points cluster around a line; a tighter cluster indicates a stronger association.

Front

What is the purpose of using a scatter plot?

Back

The purpose of using a scatter plot is to visually represent the relationship between two variables and to identify patterns, trends, or correlations.

Front

What type of variables are typically represented in a scatter plot?

Back

Scatter plots typically represent two quantitative variables.
