B01 through B11 are the 11 burgers that were evaluated with the values
being the recalled number of calories.  The variables are listed as
columns as this was a within-subjects variable.  The missing values
are because different sets of burgers were presented and evaluated
based on skewing condition.  The other variables are fairly
self-explanatory: Skew=1 for positive and Skew=-1 for negative,
order=1 for ascending and order = -1 for descending, Sequential = 1
for sequential presentation and Sequential = 0 for simultaneous
presentation.
