Scatterplots

Front

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 relationship in a scatterplot indicate?

Back

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

Front

What does a negative relationship in a scatterplot indicate?

Back

A negative relationship 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 discernible 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 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 is the purpose of a scatterplot?

Back

The purpose of a scatterplot is to visually represent the relationship between two variables and to identify trends or patterns.

Front

What does it mean if a scatterplot has a strong correlation?

Back

A strong correlation means that the data points are closely clustered around a line, indicating a strong relationship between the variables.

Front

What does it mean if a scatterplot has a weak correlation?

Back

A weak correlation means that the data points are more spread out and do not closely follow a line, indicating a weaker relationship between the 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.
