In a previous post, I asked what you would do if one person’s score changed your results? Would you throw them out? Leave them in? Does it depend on whether they support your hypothesis or not? A few people suggested collecting more data and I completely agree with their very valid points that if one…
I’ll be honest, I didn’t even know what a Quora session was until someone asked me to do one. Today, as a public service, I will tell you how you can ask me questions on Quora, what a Quora session is and what is Quora. I’ll start in what is probably the order of usefulness….
