Scatter Plots

Front

What is a scatter plot?

Back

A scatter plot is a graph that shows the relationship between two variables by displaying data points on a two-dimensional grid.

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 tends to increase.

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 tends to decrease.

Front

What does 'no association' mean in the context of a scatter plot?

Back

No association means that there is no discernible relationship between the two variables; changes in one do not affect the other.

Front

What is a nonlinear association?

Back

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

Front

How can you estimate values from a scatter plot?

Back

You can estimate values by finding the corresponding point on the plot and reading the value from the axes.

Front

What is the purpose of using scatter plots?

Back

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

Front

What does the x-axis typically represent in a scatter plot?

Back

The x-axis typically represents the independent variable, which is the variable that is manipulated or changed.

Front

What does the y-axis typically represent in a scatter plot?

Back

The y-axis typically represents the dependent variable, which is the variable that is measured or observed.

Front

How can outliers affect a scatter plot?

Back

Outliers can skew the interpretation of the data, making it difficult to identify the true relationship between the variables.
