What is a scatterplot?

Back

A scatterplot 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 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 a scatterplot?

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

What is a linear association?

Back

A linear association is a relationship between two variables that can be represented by a straight line on a scatterplot.

Front

What is a non-linear association?

Back

A non-linear association is a relationship between two variables that cannot be accurately represented by a straight line; it may curve or change direction.

Front

How can you identify a positive linear association in a scatterplot?

Back

A positive linear association is identified by points that trend upwards from left to right, indicating that as one variable increases, the other also increases.

Front

How can you identify a negative linear association in a scatterplot?

Back

A negative linear association is identified by points that trend downwards from left to right, indicating that as one variable increases, the other decreases.

Front

What is the purpose of using scatterplots?

Back

Scatterplots are used to visually assess the relationship between two variables, helping to identify correlations and trends.

Front

What is an example of a positive correlation?

Back

An example of a positive correlation is the relationship between the temperature outside and the amount of ice cream sold.
