Question

Stereograms Stereograms appear to be composed
entirely of random dots. However, they contain separate
images that a viewer can “fuse” into a three-dimensional
(3D) image by staring at the dots while defocusing the
eyes. An experiment was performed to determine whether
knowledge of the embedded image affected the time
required for subjects to fuse the images. One group of
subjects (group NV) received 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 (specifically, a draw-
ing of the object). The experimenters measured how

many seconds it took for the subject to report that he or
she saw the 3D image.
a) What two variables are discussed in this description?
b) For each variable, is it quantitative or categorical? If
quantitative, what are the units?c) The boxplots compare the fusion times for the two
treatment groups. Write a few sentences comparing
these distributions. What does the experiment show?
