Guess the Correlation

Guess the Correlation is a minimalistic browser-based game with a purpose developed in 2016 by Omar Wagih at the European Bioinformatics Institute.

[3] Players are presented with a stream of scatter plots depicting the relationship between two random variables and are asked to guess how positively correlated they are.

The game features both single and two-player modes and has a retro 8-bit design and sound effects.

[1][4] Collected guesses are used to better understand how humans perceive correlations in scatter plots by identifying features within scatter plots, such as outliers, that cause players to over or under estimate the true correlation.

[3] In the single-player mode, players are presented with a stream of scatter plots depicting the relationship between two random variables.
