Hello, I'm A930913. I noticed that you recently removed some content from Design of experiments, with [//en.wikipedia.org/w/index.php?title=Design_of_experiments&diff=595903988 this edit], without explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an edit summary. If this was a mistake, don't worry, the removed content has been restored. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. 930913(Congratulate) 17:58, 17 February 2014 (UTC)
