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 linear association in a scatter plot indicate?

Back

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

Front

What does a negative linear association in a scatter plot indicate?

Back

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

Front

What is a nonlinear association?

Back

A nonlinear association occurs when the relationship between two variables cannot be represented by a straight line.

Front

What is the range in a scatter plot?

Back

The range refers to all the possible output values (y-values) in a function or relation.

Front

What is the domain in a scatter plot?

Back

The domain refers to all the possible input values (x-values) in a function or relation.

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 can be approximated by a straight line.

Front

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

Back

No association means that there is no discernible relationship between the two variables; the data points are scattered randomly.

Front

What is the y-intercept in a linear function?

Back

The y-intercept is the point where the line crosses the y-axis, indicating the value of y when x is zero.

Front

What is a constant rate of change?

Back

A constant rate of change means that for every unit increase in x, there is a consistent increase or decrease in y.
