Scatter Plots 2

Front

What is a scatter plot?

Back

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

Front

What does a positive association in a scatter plot indicate?

Back

A positive association means that as one variable increases, the other variable also tends to increase.

Front

What does a negative association in a scatter plot indicate?

Back

A negative association means that as one variable increases, the other variable tends to decrease.

Front

What does 'no association' mean in a scatter plot?

Back

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

Front

What is a trend line in a scatter plot?

Back

A trend line is a straight line that best represents the data points in a scatter plot, showing the general direction of the data.

Front

How can you use a trend line to make predictions?

Back

You can use a trend line to estimate the value of one variable based on the value of another variable.

Front

What is a linear association?

Back

A linear association is when the data points in a scatter plot can be closely approximated by a straight line.

Front

What is a nonlinear association?

Back

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

Front

What does it mean if a scatter plot has a steep trend line?

Back

A steep trend line indicates a strong relationship between the two variables, meaning small changes in one variable result in large changes in the other.

Front

What does it mean if a scatter plot has a flat trend line?

Back

A flat trend line indicates a weak relationship between the two variables, meaning changes in one variable have little effect on the other.
