Scatterplots

Front

What is a scatterplot?

Back

A scatterplot is a graph that displays values for typically two variables for a set of data. Each point represents an observation in the dataset.

Front

What does a positive correlation in a scatterplot indicate?

Back

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

Front

What does a negative correlation in a scatterplot indicate?

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 that 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 scatterplot?

Back

A positive correlation can be identified when the points on the scatterplot 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 points on the scatterplot slope downwards from left to right.

Front

What is the purpose of using a scatterplot?

Back

The purpose of using a scatterplot is to visually represent the relationship between two quantitative variables.

Front

What is the independent variable in a scatterplot?

Back

The independent variable is the variable that is manipulated or changed in an experiment, typically plotted on the x-axis.

Front

What is the dependent variable in a scatterplot?

Back

The dependent variable is the variable that is measured or observed in an experiment, typically plotted on the y-axis.

Front

What does the slope of a scatterplot represent?

Back

The slope of a scatterplot represents the rate of change between the two variables.
