"The study level of Other is Master."
Let's suppose I am a Martian who has just landed outside your dwelling, one morning. I notice a newspaper in the yard open to the financial section and there is a reference to stocks and betas. How would attempt to explain to one very friendly Martian (who will do you no harm), what beta is, does, and why it should be considered. You can "play" off of others participants answers too. You can take me to your leader later.
