I’ve made some minor contributions from time to time in Wikipedia, a free encyclopedia on the web edited by volunteers. My previous work was on
- Binomial proportion confidence interval (September and December 2006)
- Sample (statistics) (September and October 2006)
- Simple random sample (October 2006)
Just last night, I made major revisions to an entry, Biased sample, that was written in a rather informal tone. I tried to use more rigorous definitions in the article. I also added a few comments today about weighting to correct for biases in sampling and deliberately biased samples.
I also wrote an entry in the Chance Wiki.
The nice thing about Wikipedia and the Chance Wiki is that other people can edit and improve on your work. Another person was kind enough to provide additional readings for my Chance Wiki article about expert testimony.
