Final Post

Another concept from the textbook that I found interesting was the concept of variation in the population. Since I am kind of a tech geek and go through a lot of computer equipment, I noticed that variation in the population can be a very important thing. Some products or brands have a higher failure rate than others, but it doesn’t mean that each and every product by that company is guaranteed to fail. For example, in a stack of hundreds of cds, you could have one or two that don’t work, or as many as five or six. This can help determine how reliable a product is, by basing the variation in a product that is supposed to be consistent in quality, you can make a generalization about the reliability of that product overall. However, there will still be some variation, like where the cds came from or if it was just a bad batch that got shipped out by accident.
