and Lift Angle for the Culinary Spatula," Applied Ergonomics, Vol. 33,
pp. 493-501.

Description: Results of an experiment with 4 spatula lengths (1=20cm, 2=25,
3=30, 4=40), 4 lift angles (1=15deg, 2=25, 3=35, 4=45), with 8
subjects using each spatula. Response is elapsed time to shovel and 
transfer 2000g of green beans from pan to plate.

Variables/Columns:
Length          8
Angle          16
Subject        24
Shovel Time (sec)   26-32
