What does a positive correlation indicate in a scatter plot?

Back

A positive correlation indicates that as one variable increases, the other variable also tends to increase.

Front

What does a negative correlation indicate in a scatter plot?

Back

A negative correlation indicates that as one variable increases, the other variable tends to decrease.

Front

What does no correlation mean in a scatter plot?

Back

No correlation means there is no apparent relationship between the two variables; changes in one variable do not predict changes in the other.

Front

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

Back

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

Front

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

Back

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

Front

What is an example of a positive association?

Back

An example of a positive association is the relationship between study time and test scores; as study time increases, test scores tend to increase.

Front

What is an example of a negative association?

Back

An example of a negative association is the relationship between outside temperature and the number of layers of clothing worn; as temperature increases, the number of layers worn tends to decrease.

Front

What is the purpose of a scatter plot?

Back

The purpose of a scatter plot is to visually display the relationship between two variables and to identify any patterns or correlations.

Front

What does the term 'outlier' mean in the context of a scatter plot?

Back

An outlier is a data point that differs significantly from other observations in the scatter plot, potentially indicating an anomaly.
