      about the game

      the aim of the game is simple. try to guess how correlated the two variables in a scatter plot are. the closer your guess is to the true correlation, the better.

      your guess should be between zero and one, where zero is no correlation and one is perfect correlation. no negative correlations are used in the game. here are some examples:

      
        guess the correlation is a game with a purpose. this means, while it aims to be entertaining, data on the guesses is collected and used to analyse how we perceive correlations in scatter plots. so the more people that play, the more data is generated!
      

      rules
      
      guess within 0.05 of the true correlation: +1 life and +5 coins
      guess within 0.10 of the true correlation: +1 coin
      guess within >0.10 of the true correlation: -1 life

      
      you will also receive bonus coins if you make good guesses in a row!
      


      about me
      
      i developed this game while i was a phd student studying bioinformatics at the university of cambridge and the european bioinformatics institute. this game is a side project to feed one of my many day-to-day curiosities.
      i'm always grateful for suggestions and happy to answer questions about the game or how the data will be used. so tweet me at @omarwagih or email me.
      




      usage disclaimer
      
      the analysis of the resulting data relies on true human guesses. please don't go out of your way to repeatedly and systematically guess the correct correlation (e.g. using bots). it takes away from the enjoyment of other users by spamming the score board. it's also easy to identify users that are doing this from the data and clear their name from the score board. that being said, if you find a bug or something does not work as expected, please do email me so i can sort it out.
