Time, information and performance statistics.

<p>(top left) The time spent in each round by participants rapidly decreases as can be seen with the evolution of the median (solid line) and quartiles (dashed). Shadows within the plot also show the different quartile regions when all the 25 rounds are considered (<i>Q</i>1 = 1.614, <i>Q</i>2 = 3.431, <i>Q</i>3 = 6.075). (top right) Boxplot of the time spent to make a decision as a function of the number of additional pieces information being consulted apart from the price chart displayed at the home screen. Plot shows a linear growth with slope 1.96 ± 0.12 and origin ordinate 1.89. (bottom) Success ratio of participants’ guesses does not improve when more information is being consulted. Error bars correspond to the Standard Deviation of a binomial distribution.
