Front

Describe the type of linear correlation between two variables that shows a strong positive relationship.

Back

Strong positive correlation indicates that as one variable increases, the other variable also increases.

Front

How do you find the common ratio in a geometric sequence?

Back

Divide any term by the previous term.

Front

What is the difference between an arithmetic sequence and a geometric sequence?

Back

An arithmetic sequence adds a constant difference, while a geometric sequence multiplies by a constant ratio.

Front

What does it mean if there is no correlation between two variables?

Back

No correlation means that changes in one variable do not affect the other variable.
