Scatterplots Practice #1

Front

What is a scatterplot?

Back

A scatterplot is a type of graph that shows the relationship between two variables by displaying data points on a two-dimensional grid.

Front

What does a positive association in a scatterplot indicate?

Back

A positive association means that as one variable increases, the other variable also tends to increase.

Front

What does a negative association in a scatterplot indicate?

Back

A negative association means that as one variable increases, the other variable tends to decrease.

Front

What does 'no association' mean in a scatterplot?

Back

No association means there is no clear relationship between the two variables; changes in one do not affect the other.

Front

What is correlation?

Back

Correlation is a statistical measure that describes the extent to which two variables change together.

Front

What is a positive correlation?

Back

A positive correlation occurs when two variables move in the same direction.

Front

What is a negative correlation?

Back

A negative correlation occurs when two variables move in opposite directions.

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 clear relationship.

Front

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

Back

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

Front

How can you estimate values from a scatterplot?

Back

You can estimate values by finding the corresponding point on the graph and reading the value from the axes.
