Constructing 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 it mean if a scatter plot shows a linear relationship?

Back

A linear relationship in a scatter plot indicates that as one variable increases or decreases, the other variable does so in a consistent manner, forming a straight line.

Front

What does it mean if a scatter plot shows a nonlinear relationship?

Back

A nonlinear relationship in a scatter plot indicates that the relationship between the variables does not form a straight line, and the rate of change varies.

Front

What is an increasing association in a scatter plot?

Back

An increasing association means that as one variable increases, the other variable also increases, typically resulting in an upward slope.

Front

What is a decreasing association in a scatter plot?

Back

A decreasing association means that as one variable increases, the other variable decreases, typically resulting in a downward slope.

Front

How can you identify a nonlinear association in a scatter plot?

Back

A nonlinear association can be identified by looking for curves or patterns that do not form a straight line.

Front

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

Back

No association means that there is no discernible pattern or relationship between the two variables, and the data points are scattered randomly.

Front

In Scatter Plot C, as the altitude increases, what happens to atmospheric pressure?

Back

As altitude increases, atmospheric pressure decreases.

Front

What is the purpose of using scatter plots in data analysis?

Back

Scatter plots are used to visually represent the relationship between two variables, helping to identify trends, correlations, and potential outliers.

Front

What are outliers in a scatter plot?

Back

Outliers are data points that fall far away from the general pattern of the other data points in a scatter plot, indicating unusual values.
