# Multivariate tests {% embed url="" %} A multivariate test — or multidimensional test — is a `Test` experiment with more than one dimension. It lets you test all combinations of the arms of each dimension. For example, you can have one dimension called `Button color` with three arms — `Red`, `Blue`, and `Green` — and another dimension called `Button text` with three arms — `Sign up`, `Get access`, and `Request access`. You can embed the test into a `String` flag, e.g. one called `buttonColor` that controls the color of your call-to-action button, then select the `Button color` dimension, and then set flag values for each arm. And you can embed the same test into another `String` flag, e.g. one called `buttonText` that controls the text of your call-to-action button, but this time select the `Button text` dimension, and then set flag values for each arm. This will test all 9 combinations of button color and button text. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
