Scatter Plots Association

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 strong association in a scatter plot indicate?

Back

A strong association indicates that the data points are closely clustered together, suggesting a clear relationship between the two variables.

Front

What is a positive association in a scatter plot?

Back

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

Front

What is a negative association in a scatter plot?

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 discernible relationship between the two variables; the data points are scattered randomly.

Front

What is correlation?

Back

Correlation is a statistical measure that describes the extent to which two variables change together.

Front

What is a strong positive correlation?

Back

A strong positive correlation indicates that the data points closely follow a straight line with a positive slope.

Front

What is a weak negative correlation?

Back

A weak negative correlation indicates that there is a slight downward trend in the data points, but they are not closely clustered.

Front

How can you determine the type of association from a scatter plot?

Back

You can determine the type of association by observing the direction of the trend of the data points: upward for positive, downward for negative, or no clear trend for no association.

Front

What is the significance of the slope in a scatter plot?

Back

The slope indicates the direction and steepness of the relationship between the two variables; a positive slope indicates a positive association, while a negative slope indicates a negative association.
