1) Business uses stats to make predictions, increase their profits.
2) We all use stats, everytime we make an informed guess about
the world around us. E.g. (those clouds are dark, it's probably going
to rain today) -Not very sophisticated, but that's where it starts.
3) When you read a poll in the newspaper, a confidence interval is
often given. It tells you how confident you can be in the poll.
4) Public safety uses stats -to make sure theres a very small chance
something might go wrong
5) Probability can be fun and challenging (See Monty Carlo Paradox)
Uses Of Statistics
I took a statistics class and I found it to be useful in
1. finding the biases in political or media polls
2. experiments
3. approximating how many boxes of pizzas to buy
4. gambling
5. if asking a guy/girl out will be worth a shot ;)
1. Weather Forecasts
The computer models are built using statistics that compare prior weather conditions with current weather to predict future weather.
2. Emergency Preparedness
Emergency management agencies move into high gear to be ready to rescue people. Emergency teams rely on statistics to tell them when danger may occur.
3. Predicting Disease
Lots of times on the news reports, statistics about a disease are reported. If the reporter simply reports the number of people who either have the disease or who have died from it, it's an interesting fact but it might not mean much to your life. But when statistics become involved, you have a better idea of how that disease may affect you.
For example, studies have shown that 85 to 95 percent of lung cancers are smoking related. The statistic should tell you that almost all lung cancers are related to smoking and that if you want to have a good chance of avoiding lung cancer, you shouldn't smoke.
4. Medical Studies
Scientists must show a statistically valid rate of effectiveness before any drug can be prescribed. Statistics are behind every medical study you hear about.
5. Genetics
Many people are afflicted with diseases that come from their genetic make-up and these diseases can potentially be passed on to their children. Statistics are critical in determining the chances of a new baby being affected by the disease.
6. Political Campaigns
Whenever there's an election, the news organizations consult their models when they try to predict who the winner is. Candidates consult voter polls to determine where and how they campaign. Statistics play a part in who your elected government officials will be
7. Insurance
You know that in order to drive your car you are required by law to have car insurance. If you have a mortgage on your house, you must have it insured as well. The rate that an insurance company charges you is based upon statistics from all drivers or homeowners in your area.
8. Consumer Goods
Wal-Mart, a worldwide leading retailer, keeps track of everything they sell and use statistics to calculate what to ship to each store and when. From analyzing their vast store of information, for example, Wal-Mart decided that people buy strawberry Pop Tarts when a hurricane is predicted in Florida! So they ship this product to Florida stores based upon the weather forecast.
9. Quality Testing
Companies make thousands of products every day and each company must make sure that a good quality item is sold. But a company can't test each and every item that they ship to you, the consumer. So the company uses statistics to test just a few, called a sample, of what they make. If the sample passes quality tests, then the company assumes that all the items made in the group, called a batch, are good.
10. Stock Market
Another topic that you hear a lot about in the news is the stock market. Stock analysts also use statistical computer models to forecast what is happening in the economy.

Well, I play a trading card game known as Magic: The Gathering. The basic goal of the game is to construct a deck out of different kinds of cards, and then pit it against an opponents deck, and (hopefully) win. Most people just take all their favorite cards and put them in a deck. This is fine, but if you want to succeed in tournaments, you need to do some statistical math. For example, one rule is that you can only have a maximum of four cards of the same kind in the deck (with the exception being basic lands, which make everything tick). Another rule is that the deck must be a minimum of 60 cards (40 in special cases). Right off the bat, just with these two rules, we need to do some calculation. Many decks have cards that work together in special ways, or combinations. For a tournament player, it is essential that s/he can calculate the odds of getting the right cards so that the deck functions properly. This is why most decks are cut down to meet the 60 card minimum- it offers the best chance of drawing the needed combinations as quickly as possible. So, lets say that you have a three card combination. If the decks main focus is on completing this combo, then most players will put in four copies of each necessary card in the deck. Quick math tells us that 4/60 = 1/15, in other words, you have a one in fifteen chance of drawing one copy of the four of any one kind of card if you draw one card at random. At the beginning of the game, players draw seven cards, which constitutes their initial hand. Assuming you make the first play (thus, you do not draw a card on your first turn), you have a 7/15 chance of holding one copy of one type of card. Using this probability, you can find how quickly you should be able to summon your combo. Another important use of probability is the Mana Curve. Remember when I said lands make this game tick? Well, lands produce mana, which is where the term "Mana Curve" comes from. Mana is like a currency within the game. You need a certain amount to play other cards. In order to maximize the effectiveness of a deck, it needs to fit the Mana Curve. So, back to probability. In this game, every time it is your turn, you draw a card, and you are allowed to play one land per turn. Every turn, a land can be used to produce mana once, but then you typically have to wait until your next turn to use it again. This being said, you should ideally have your Mana Curve set so that you could use all of your mana every turn, so that you get the most magic for your mana, so to speak. Now, tournament players often use cards that accelerate their mana curve, but most decks fit into this perfect set of numbers that have been calculated out: 24 lands, 9 cards that cost 1 mana, 8 that cost 2, 7 that cost 3, 6 that cost 4, and 6 that cost 5+. The reasoning for this is simply that 24/60 = 4/10. This basically means that you are virtually guaranteed to be able to play a land card every turn until turn 5, where upon things are no longer certain, but at least you've had four turns to marshal your initial forces. The key to making sure that you can play for maximum mana output every turn now lies in being sure that the things that cost the right amount show up in time. This is achieved through probability, too. Now, you know that you will have 7 cards to begin with. 7*9=63, so you know that if you have nine cards that cost one mana, you will have virtually a %100+ chance of being able to play (unlike having only 8, because 8*7=56, and 56/60 isn't equal to 1+, or a sure bet. However, the odds are still arguably good). The same logic is used in finding the other numbers. The key to winning in tounaments often comes down to if you can increase your own tempo and mana curve, and disrupt your opponents, thus making probability crucial to winning. Hope this example helped!

1. Research papers. Very helpful to support an opinion
2. Raising public awareness over a disease, problem or significant desparity btw groups
3. Nonsense/ Plain fun I guess with your friends
4. It could also be like one of those wierd hobbies that *some people* are programmed to do with their precious time
5. Name that statistics....the charades game? lol I dunno

Yeah I find statistics interesting. The new study ACCOMPLISH has shown statistically an ACEI + CCB is superior than ACEI + b blocker when it comes to hypertension. Who would have known? Thanks statistics!
