Scatter Plot Description and vocab

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 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 non-linear association in a scatter plot?

Back

A non-linear association means that the data points do not follow a straight line and may curve or cluster in a different pattern.

Front

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

Back

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

Front

What is the line of best fit in a scatter plot?

Back

The line of best fit is a straight line that best represents the data on a scatter plot, showing the general direction of the data points.

Front

How can you determine if a scatter plot has no correlation?

Back

A scatter plot has no correlation if the data points are scattered randomly without any discernible pattern.

Front

What does it mean if a scatter plot shows a strong correlation?

Back

A strong correlation means that the data points are closely clustered around the line of best fit, indicating a strong relationship between the variables.
