  • Next define the parameters that will change between control and test groups. You will specify the value for these parameters in the next step

    Experiment Parameters

  • By default, each experiment runs in its own layer. When you want to exclude any users exposed to other experiments, check the Select an existing layer option to see what percentage of users are available for this experiment. In the example below, 40% of the users in a layer are available for this experiment. This means that you can define the experiment size to be a percentage that's less than or equal to 40%.

  • After choosing the layer, you can set the paramter values for each group in the experiment, and add groups if you wish.

Experiment Layers and Parameters

  • Finally, select the primary metrics that are part of your hypothesis for this experiment.
