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 correlation in a scatter plot indicate?

Back

A positive correlation indicates that as one variable increases, the other variable also tends to increase.

Front

What does a negative correlation in a scatter plot indicate?

Back

A negative correlation indicates that as one variable increases, the other variable tends to decrease.

Front

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

Back

'No association' means that there is no discernible relationship between the two variables being plotted.

Front

What is a linear association in a scatter plot?

Back

A linear association means that the data points can be approximated by a straight line.

Front

What is a nonlinear association in a scatter plot?

Back

A nonlinear association means that the relationship between the variables cannot be accurately represented by a straight line.

Front

How can you identify a scatter plot with no association?

Back

A scatter plot with no association will show data points that are randomly scattered without any clear pattern.

Front

What does it mean if a scatter plot shows a steep slope?

Back

A steep slope in a scatter plot indicates a strong relationship between the two variables, whether positive or negative.

Front

What is the purpose of using scatter plots?

Back

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

How can you determine the age of a tree from a scatter plot?

Back

You can determine the age of a tree by locating its height on the y-axis and finding the corresponding age on the x-axis.
