| The data is for weekly sales in the sporting goods department at
a Wal*Mart store in the Northeast.
Peak values, I.e. spikes, usually occur at holiday periods or other
special events. Sudden dips in the
data often reflect low stock. Week 1
is the first week of February 2003.
To show continuity, week 1 of 2004 is represented as week 53 since
week 53 represents the start of the 2004 fiscal year. Dollar values are
adjusted in order to disguise true sales figures, but trends in the data are
retained for analysis purposes. Note that for 2002-2003 data, Wal*Mart used
53 weeks for their fiscal year data. |
