Dataset Name: Lew (Beam Deflection Data)
|
|
|
|
Description: This is an observed/"real world" data set
|
|
consisting of 200 deflections of a steel-concrete
|
|
beam while subjected to periodic pressure.
|
|
The experimenter was H. S. Lew of the
|
|
Center for Building Technology at NIST.
|
|
We here use this data to test accuracy
|
|
in summary statistics calculations.
