Front

What is correlation?

Back

Correlation is a statistical measure that describes the extent to which two variables change together. A positive correlation means that as one variable increases, the other also increases, while a negative correlation means that as one variable increases, the other decreases.

Front

What are the types of correlation?

Back

The types of correlation include positive correlation, negative correlation, and no correlation.

Front

What does a positive correlation indicate?

Back

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

Front

What does a negative correlation indicate?

Back

A negative correlation indicates that as one variable increases, the other variable tends to decrease.

Front

What does 'no correlation' mean?

Back

'No correlation' means that there is no predictable relationship between the two variables.

Front

What is a scatterplot?

Back

A scatterplot is a graph that displays values for typically two variables for a set of data. It helps to visualize the relationship between the variables.

Front

What does a linear relationship look like on a scatterplot?

Back

A linear relationship on a scatterplot appears as a straight line, indicating a consistent rate of change between the two variables.

Front

What does a nonlinear relationship look like on a scatterplot?

Back

A nonlinear relationship on a scatterplot appears as a curve or a cluster of points that do not form a straight line.

Front

How can you identify a positive correlation in a scatterplot?

Back

A positive correlation can be identified in a scatterplot when the points trend upwards from left to right.

Front

How can you identify a negative correlation in a scatterplot?

Back

A negative correlation can be identified in a scatterplot when the points trend downwards from left to right.
