Guess The Correlation

You and a group of friends can play with this experiment as we ran it by following these instructions (assuming you have Meteor installed):

  1. Download the repository (and unzip). Alternatively, from terminal just run:

git clone
  1. Go into the folder with cd guess-the-correlation

  2. Install the required dependencies by running meteor npm install

  3. Edit the admin password in the settings file local.json to something you like.

  4. Run the local instance with meteor --settings local.json

  5. Go to http://localhost:3000/admin (or whatever port you are running Meteor on).

  6. login with the credentials username: admin and the password you have in local.json

  7. Start a new batch with whatever configuration you want (see the example configuration).

Example Config:

First, you have to enter the Configuration mode instead of the Monitoring model in the admin UI.

This will allow you to configure the experiment: Factors, Lobby, and Treatments:

Now, you have the option to create your own configuration (see below) or load an example configuration by clicking on import and then choosing the file ./example-config.yaml. Loading the example configurations will choose some example values for the factors (i.e., independent variables), lobby configuration, and few treatments.

Finally, you can go back to the Monitoring mode:

Now the Batchs tab make sure you add a new batch, add the treatments you want, choose your lobby configurations, and then start the batch.

Go to http://localhost:3000/ and enjoy! If you don't have 3 friends to play with you, you always can use the new player button in development (for more details see this), which can add an arbitrary number players to the experiment while staying in the same browser (i.e., no need to open different browsers).
