:TITLE "Michelson" 
:ABOUT "Michelson's measurements of the velocity of light in air.

Data are 100 determinations of the velocity of light in air reported in 5 runs of 20 trials.  Each trial may be a summary of several experimental observations.  Velocities are in km/sec and have had 299,000 subtracted from them.  

The true value (i.e., the value based on the currently accepted speed of light) appropriate for comparison is reported by Stigler to be 734.5. (Stigler, Stephen M. (1977) Do Robust Estimators Work with Real Data?,
The Annals of Statistics, 5:4, p 1075). 

Balanced one-way, five-level data appropriate for ANOVA. Data obtained from Datadesk which used these data with publisher's permission."
