What does a positive correlation indicate in a scatterplot?

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 scatterplot?

Back

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

Front

What does 'no correlation' mean in the context of scatterplots?

Back

No correlation means there is no discernible relationship between the two variables; the data points do not show any trend.

Front

What is a linear relationship in a scatterplot?

Back

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

Front

What is a non-linear relationship in a scatterplot?

Back

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

Front

How can you identify a positive correlation in a scatterplot?

Back

A positive correlation can be identified when the data points slope upwards from left to right.

Front

How can you identify a negative correlation in a scatterplot?

Back

A negative correlation can be identified when the data points slope downwards from left to right.

Front

What does it mean if a scatterplot shows a cluster of points?

Back

A cluster of points indicates that there is a strong relationship between the variables in that specific range.

Front

What is the purpose of using scatterplots?

Back

Scatterplots are used to visually assess the relationship between two variables and to identify trends, patterns, or outliers.
