Use the link below to see the results of an experiment on the effect of prior information on the time to fuse random dot stereograms. One group (NV) was given either no information or just verbal information about the shape of the embedded object. A second group (group VV) received both verbal information and visual information (e.g., a drawing of the object). Does the median time prove to be greater for the NV group? Compare your results to those from a two-sample t-test.
