Naked Statistics. Stripping the Dread from the Data. [Conspect III]

Mathematics - accuracy science. Statistics - not accuracy science. But we can get lie as accuracy value. And we can get truth as determine with low accuracy.

Statistics isn't accuracy and possible to use it to do lie. But it's possible for mathematics too.

Difficult systems can provide lie, because nobody don't know how it works totally! But possible what they are do it on the high accuracy level.

Example of the lie: people think what "Output" is result from "Employment" count only ... But it isn't truth ... We are determine "Output" as sum of all things and it's result from many values where each values is result of difficult system(s) ... 

Politician A (the challenger): “Our schools are getting worse! Sixty percent of our schools had lower test scores this year than last year.”

Politician B (the incumbent): “Our schools are getting better! Eighty percent of our students had higher test scores this year than last year.”

Tip: school have various count of students.

Politician A (a populist): “Our economy is in the crapper! Thirty states had falling incomes last year.”

Politician B (more of an elitist): “Our economy is showing appreciable gains: Seventy percent of Americans had rising incomes last year.”

IMPORTANT: Need to use right measure each times, because we can do mistake in the conclusions. People is important here, but schools isn't important!

How to do manipulation with average and median? George W. Bush and his administration say what they can decrease tax for 92 millions people to 1000$ as average. But really it's only around 100$ as median. It's only one that important for peoples.

But average important for effects in the economics. If I'm G.W. Bush, I know that will lost average 1000$ per people from the tax. Or if need to show that average american will save many money.

Nominal cost is cost that not include inflation. Real with it.

Hollywood, nominal rate:

1. Avatar (2009)
2. Titanic (1997)
3. The Dark Knight (2008)
4. Star Wars Episode IV (1977)
5. Shrek 2 (2004)

Real rate:

1. Gone with the Wind (1939)
2. Star Wars Episode IV (1977)
3. The Sound of Music (1965)
4. E.T. (1982)
5. The Ten Commandments (1956)

There is a common business aphorism: “You can’t manage what you can’t measure.” True. But you had better be darn sure that what you are measuring is really what you are trying to manage.

Conclusions:

1. Check statistical mistake more easy then mathematics mistake. They are on the surfaces;
2. Possible to get answers with descriptive statistics if I have truth determining about that I need;
3. Possible to show for various people information that they are like;
4. Possible to who what are you need too ... ;
