On average, the length of a customer's visit to a bookstore in this study falls within
a range of 6-10 minutes, with Bookstore #10 having the largest average visit at
approximately 10 minutes.

Customers spend an average of about 4 and a half minutes in a section before
moving on to another section. This average varies by no more than a minute across
the four bookstores.
 
 
 

The average lengths of customers' visits to the two bookstores with ambient and focal
light were 7 minutes and 10 minutes while the two bookstores with solely ambient light
had averages of 8 minutes and 9 minutes. These graphs reveal no correlation between
quality of light and customers' browsing times.
 
 
 

When we realized lighting was not a primary determinant of browsing patterns in the four
bookstores studied, we analyzed the correspondence between browsing time and the
bookstore's location. Bookstores in the downtown area had average browsing lengths
of approximately 8 minutes and 10 minutes. Bookstores in outlying areas further from
downtown browsing averages at 7 minutes and 9 minutes.
 
 
 

This graph reveals the popularity of the magazine section in Bookstore #2, which
was the only bookstore that sold magazines. Customers spent an average of 7
minutes browsing in the magazine section versus an average of 3 minutes spent
browsing in other sections of the store.
 
 
 

This graph illustrates the amount of time customers spent browsing in the magazine
section of Bookstore #2. Customers spent an average of 8 minutes browsing
throughout the entire store, including the magazine section. When the time
customers spent browsing in the magazine section is eliminated from the caluclation,
this average drops to 4 minutes which reveals that the browsing in Bookstore #2's
non-magazine sections is actually less than the browsing averages in equivalent
sections in the other three stores.
