How to Make an Introduction to a Reflective Essay?
Please read that instead. Your friends and colleagues are talking about something called "Bayes' Theorem" or "Bayes' Rule", or something called Bayesian reasoning. They sound really enthusiastic about it, too, so you google and find a webpage about Bayes' Theorem and The page you found gives a definition of it, but it doesn't say what it is, or why it's useful, or why your friends would be interested in it.
It looks like this random statistics thing. So you came here. Maybe you don't understand what the equation says. Maybe your friends are all wearing Bayes' Theorem T-shirts, and you're feeling left out. Maybe you're a girl looking for a boyfriend, but the boy you're interested in refuses to date anyone who "isn't Bayesian".
What matters is that Bayes is cool, and if you don't know Bayes, you aren't cool. Why does a mathematical concept generate this strange enthusiasm in its students? What is the so-called Bayesian Revolution now sweeping through the sciences, which claims to subsume even the experimental method itself as a special case?
What is the secret that the adherents of Bayes know? What is the light that they have seen? Soon you will know. Soon you will be one of us.
While there are a few existing online explanations of Bayes' Theorem, my experience with trying to introduce people to Bayesian reasoning is that the existing online explanations are too abstract.
Bayesian reasoning is very counterintuitive. People do not employ Bayesian reasoning intuitively, find it very difficult to learn Bayesian reasoning when tutored, and rapidly forget Bayesian methods once the tutoring is over.
This holds equally true for novice students and highly trained professionals in a field. Bayesian reasoning is apparently one of those things which, like quantum mechanics or the Wason Selection Test, is inherently difficult for humans to grasp with our built-in mental faculties.
Or so they claim. Here you will find an attempt to offer an intuitive explanation of Bayesian reasoning - an excruciatingly gentle introduction that invokes all the human ways of grasping numbers, from natural frequencies to spatial visualization.
The intent is to convey, not abstract rules for manipulating numbers, but what the numbers mean, and why the rules are what they are and cannot possibly be anything else.
When you are finished reading this page, you will see Bayesian problems in your dreams. Here's a story problem about a situation that doctors often encounter: A woman in this age group had a positive mammography in a routine screening.
What is the probability that she actually has breast cancer? What do you think the answer is? If you haven't encountered this kind of problem before, please take a moment to come up with your own answer before continuing.
If you're not sure, I suggest using parentheses. Here's an alternate version of the problem on which doctors fare somewhat better: If women in this age group undergo a routine screening, about what fraction of women with positive mammographies will actually have breast cancer?
If 10, women in this age group undergo a routine screening, about what fraction of women with positive mammographies will actually have breast cancer? The correct answer is 7. Out of 10, women, have breast cancer; 80 of those have positive mammographies. From the same 10, women, 9, will not have breast cancer and of those 9, women, will also get positive mammographies.
Of those 1, women with positive mammographies, 80 will have cancer. To put it another way, before the mammography screening, the 10, women can be divided into two groups:Social networking is a tool used by people all around the world. Its purpose is to promote and aid communication.

However, this type of technology might be doing more harm than good. Social and Political Recognition. Acts of recognition infuse many aspects of our lives such as receiving a round of applause from a rapt audience, being spotted in a crowded street by a long-forgotten friend, having an application for a job rejected because of your criminal record, enjoying some words of praise by a respected philosophy professor, getting pulled over by the police because you.
