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 does 'no association' mean in the context of scatter plots?

Back

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

Front

How can you identify a positive association in a scatter plot?

Back

A positive association can be identified by a pattern where points slope upwards from left to right.

Front

How can you identify a negative association in a scatter plot?

Back

A negative association can be identified by a pattern where points slope downwards from left to right.

Front

What is a linear relationship in a scatter plot?

Back

A linear relationship is when the data points form a straight line, indicating a consistent rate of change between the variables.

Front

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

Back

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

Front

What does the slope of a line in a scatter plot represent?

Back

The slope represents the rate of change between the two variables; a steeper slope indicates a stronger relationship.

Front

What is the purpose of using scatter plots?

Back

Scatter plots are used to visually assess the relationship between two variables and to identify trends, patterns, or correlations.
