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 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 there is no apparent relationship between the two variables; changes in one do not affect the other.

Front

How can you identify a positive correlation in a scatterplot?

Back

A positive correlation can be identified by a pattern where 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 by a pattern where 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 any trends or correlations.

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 two variables in that range.

Front

What is an outlier in a scatterplot?

Back

An outlier is a data point that lies far away from the other points in the scatterplot, indicating it may not fit the general trend.

Front

What is the independent variable in a scatterplot?

Back

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