On this Picostat.com statistics page, you will find information about the SpaceShuttle data set which pertains to Space Shuttle O-ring Failures. The SpaceShuttle data set is found in the vcd R package. You can load the SpaceShuttle data set in R by issuing the following command at the console data("SpaceShuttle"). This will load the data into a variable called SpaceShuttle. If R says the SpaceShuttle data set is not found, you can try installing the package by issuing this command install.packages("vcd") and then attempt to reload the data. If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the SpaceShuttle R data set. The size of this file is about 578 bytes.
Space Shuttle O-ring Failures
Data from Dalal et al. (1989) about O-ring failures in the NASA space
shuttle program. The damage index comes from a discussion of the data
by Tufte (1997).
A data frame with 24 observations and 6 variables.
Number of space shuttle flight.
temperature during start (in degrees F).
did any O-ring failures occur? (no, yes).
how many (of six) 0-rings failed?.
