10 Everyday Reasons Why Statistics Are Important
Statistics
are sets of mathematical equations that are used to analyze what is
happening in the world around us. You've heard that today we live in the
Information Age where we understand a great deal about the world around
us. Much of this information was determined mathematically by using
statistics. When used correctly, statistics tell us any trends in what
happened in the past and can be useful in predicting what may happen in
the future.
Let's look at some examples of how statistics shape your life when you don't even know it.
1. Weather Forecasts
Do
you watch the weather forecast sometime during the day? How do you use
that information? Have you ever heard the forecaster talk about weather
models? These computer models are built using statistics that compare
prior weather conditions with current weather to predict future weather.
2. Emergency Preparedness
What
happens if the forecast indicates that a hurricane is imminent or that
tornadoes are likely to occur? 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.
