It seems likely that the first people to study probability were motivated by gambling.
This particular article will not prepare anyone to win at a casino. However, the foundation to avoid losing is to realize that the professionals already know the odds.
Fun [but long] article introducing basic mathematical concepts in probability…

Statistics Sells. That’s why it’s being used to also track wellbeing & happiness!
University of Pennsylvania duo Betsey Stevenson and Justin Wolfers have analysed happiness surveys conducted in 132 countries. Their statistical study shows the impact of economic growth on happiness.
For example, on a 0to10 life satisfaction scale, respondents in Mali and Ethiopia place themselves between 3 and 4; residents of Egypt, South Africa and Portugal put themselves between 5 and 6; and people in Australia, the US and most other developed countries place themselves between 7 and 8. A 10 per cent increase in GDP buys as much additional happiness in a rich country as a poor one.
So, money can buy you happiness…statistically speaking!

Statistics is the study of data analysis; there are two kinds of statistics descriptive and inferential. Graphs and charts, averages, dispersion of data, probability and its distributions etc.
At this link you can find some good article about statistics.

Andrew Castillo Nov. 22, 2011Perusing the site, I take issue with the claim (under Limitations of Statistics) that “Statistical methods are best applicable on quantitative data.” The use of dummy variables in regression analysis is common and as far as I know their use doesn't make the regression model any less applicable.

Human life is full of decisions, including significant choices about what to believe. Although everyone prefers to believe what is true, we often disagree with each other about what that is in particular instances… [read the full article]


Mario Zolt Nov. 23, 2011We don't know if it's a fact or not, the only thing that we know for sure is that we don't know, because nobody know what is inside a star.

srini n Dec. 9, 2011What is posted above makes for interesting reading! I am neither a logician. statistician or a philosopher. Just a curious layman. But what I recollect as having read some 20 yrs ago or more (cant remember the book title) is truth is independent of proof and acknowledgement. Like if it had rained in a Brazilian forest at 8 am today, it happens to be a truthful fact whether anyone was there to notice it or record it. The distinction between fact and truth was made in the book I read but presently I am not able to recollect what it was. But what i do recall is fact is considered a limited context sensitive reality whereas truth is something which transcends time and space. I wish I cd recall more or cite the source but I am sorry my memory fails me (as it does quite often!)

Social networks such as facebook and YouTube as well as great resources including Wikipedia and WolframAlpha are here to stay so that educators must use them in the teaching process.
Many academics are posting great educational videos and materials online. The only problem is to sort the good ones from the rest and present them in an organized manner.
This effort is being done by: http://Utubersity.com which presents the best educational videos available on YouTube (including Statistics) in an organized, easy to find way to watch and learn.
They are classified and tagged in a way that enables people to find these materials more easily and efficiently and not waste time browsing through pages of irrelevant search results.
The website also enhances the experience using other means such as recommending related videos, Wikipedia content and so on.
There’s also a Spanish version called http://utubersidad.com

Logical Reasoning
Logical reasoning is the process which uses arguments, statements, premises and axioms to define weather a statement is true or false, resulting in a logical or illogical reasoning. In today’s logical reasoning three different types of reasoning can be distinguished, known as deductive reasoning, inductive reasoning and abductive reasoning based on respectively deduction, induction and abduction.
