Scatter Plot 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 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 is no association in a scatter plot?

Back

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

Front

What is a linear relationship in a scatter plot?

Back

A linear relationship is when the data points can be approximated by a straight line, indicating a consistent rate of change.

Front

What is a non-linear relationship in a scatter plot?

Back

A non-linear relationship is when the data points do not form a straight line, indicating that the rate of change varies.

Front

What does a strong association mean in a scatter plot?

Back

A strong association means that the data points are closely clustered around a line or curve, indicating a clear relationship.

Front

What does a weak association mean in a scatter plot?

Back

A weak association means that the data points are more spread out and do not closely follow a line or curve.

Front

How can you identify a linear relationship in a scatter plot?

Back

You can identify a linear relationship by observing if the data points form a straight line or closely follow a linear trend.

Front

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

Back

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