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 association in a scatter plot indicate?

Back

A positive association indicates 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 indicates 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 being plotted.

Front

How can you determine the number of data points in a scatter plot?

Back

You can determine the number of data points by counting the individual points plotted on the graph.

Front

What is the purpose of a scatter plot?

Back

The purpose of a scatter plot is to visually represent the relationship between two variables and to identify trends or patterns.

Front

What does it mean if the points in a scatter plot are tightly clustered?

Back

If the points are tightly clustered, it indicates a strong relationship between the two variables.

Front

What does it mean if the points in a scatter plot are widely spread out?

Back

If the points are widely spread out, it indicates a weak relationship between the two variables.

Front

What is the correlation coefficient?

Back

The correlation coefficient is a numerical measure that indicates the strength and direction of a linear relationship between two variables.

Front

What is an outlier in a scatter plot?

Back

An outlier is a data point that lies significantly outside the range of the other data points, potentially indicating an anomaly.
