This data is not from the Michelson-Morley experiment but from Michelson's measurement of the speed of light. See MICHELSON, A. A. (1882). Experimental determination of the velocity of light made at the United States Naval Academy, Annapolis. Astronomic Papers 1 pp. 109-145 U.S. Nautical Almanac Office, or S. M. Stigler (1977) Do robust estimators work with real data? Annals of Statistics 5, 1055–1098.

Boxplot representing Michelson's data on the speed of light. It consists of five experiments, each made of 20 consecutive runs. Note that the oblique line is incorrect, and probably due to a bug in the Mediawiki software/SVG converter. The graphic was created by User:Schutz for Wikipedia on 28 December 2006, using the R statistical project. The program that generated the graphic is given below; the data and the idea are from the R help page for the morley dataset (see help(morley)). The graph was exported in postscript format, converted to SVG using the pstoedit command, and the layout was slightly modified using Inkscape before upload.
data(morley) morley$Expt <- factor(morley$Expt) morley$Run <- factor(morley$Run) attach(morley) postscript("Michelsonmorley-boxplot.ps", paper="special", height=6, width=6, horizontal=F) par(las=1) par(mar=c(5.1, 5.1, 2.1, 2.1)) par(font=2) par(font.axis=2) boxplot(Speed ~ Expt, xlab = "Experiment No.", ylab="Speed of light (km/s minus 299,000)") abline(h=792.458, lty=3) dev.off()
