the world we live in is a wash with data
that comes pouring in from everywhere around us
on is own this data is just noise and confusion
to make sense of data
to find the meaning in this
we need a powerful brunch of science STATISTICS
believe me thats nothing boring about statistics , especially not today when we
can make the data
seen
with statistics we can really make sense of the world
and there is more
with statistics that data deluge as it been called , is leading us to an ever
greater understanding
of life on Earth and the Universe beyond
and thanks to the incredible power of today's computers it may
fundamentally transformed the process of scientific discovery
I kid you not
statistics is now the sexiest subject around
Sztokholm, Szwecja
did you know that there is a one million boats in Sweden
thats one boat per nine people
is the highest number of boats per person in Europe
Sweden also has .. the most McDonalds per person in Europe
..... the most computers per person in Europe
.. the most nuclear reactor per person in Europe
being a statistician you dont like telling your profession at dinner parties
but really
statistician shouldn't be shy becouse everyone wants to understand whats going on
and statystics
gives us a perspective on the world we live in that we cant get in any other way
the average person spends 24 years of their life asleep
statistics tells us whether the things we think
and believe are actually true
most men think theyre better drivers than women
but they have almost double the fatal accidens per mile driven
a statystics are far more useful
than we usually like to admit
in the last recession I was listen this famous calling to a talk-radiostation
the man complain
in times like this when unemployment raised up to a thirteen percent and income
is fallen by five percent and suicide raised up climbing
I get so angry that the government is wasting money on things like
connection of statystics
Im not officially a statystician
strictly speaking my field is global health
but i got really obsessed with stats when I realized how much people in
Sweden just don't know about the rest of the world
I started in our medical university Karolinska Instytut an undergraduate
course called global health
these students coming to our section at the highest grade you can get in the
swedish college system so i thought maybe they know everything i'm going to
teach them about
so I did the pretest
when they came and one of the question
from which I learned a lot was this one: which country has the highest child
mortality of this five pairs
I wont put you at the test here but is Turkey which is highest, there Poland
Russia,Pakistan and South Africa
and these were the results of the swedish students
one point eight right answer of the five possible
that means that there was a place for a professor of international health
and for my course
but one late night when I was compiling the report I really realised
my discovery , I have shown that swedish top students know statisticaly
significantly less about the world than the chimpanzees
because the chimpanzee would score
half right, if I gave them two bananas which Sri Lanka or Turkey
would be right half of the cases
but the students are not that. I did also an unethical study of the
professors of the Karolinska Instytut
that hands of Nobel Prize in medicine and they are on par with the
chimpanzee there
today there's more information accessible than ever before
and I work with my team at the Gapminder Fundation using new tools
that help everyone make sense of the changing world
we draw all the masses of data thats now freely available from international
institutions like the UN and the World Bank
and its become my mission to share the insights from this data
with anyone who listen
and to reveal
how statistics is nothing to be frighten
Im going to provide you a view
of the global health situation
across mankind
and Im going to do that
in a hopefully enjoyable way so relax
so we did this software which displaced it like this
every bubble here is a country
this is China
this is India
the size of the bubble is the population and
I done the stage of race here
between the sort of yellowish Ford here
and the red Toyota down there
and the brownish Volvo
the Toyota has a very bad start down here, and US Ford is going offroad
back, and the Volvo is doing quite fine
this is the war, the Toyota got off tracking out to our best country
coming on to a healthier side of Sweden
thats it why I sold the Volvo and both the Toyota

the city of san francisco

opening upbeat state government every
even the police department is releasing olympics crime reports
is sufficient crime
turned into a wonderfully attractive man by two of the city's computer whizzes
it's communities that these pics connection
crime's going as a matter of
crime reports from the san francisco police department
uh... showing young dot sohn maps uh... for citizens to be able to see patterns
of crime around their neighborhoods in san francisco
the map is not just about individual crimes but about broader patterns the
show you where crime is clustered
around the city which areas of high crimes which a resume relatively low

put the crime maps jealous is the relationship between

this was a higher up the helpful s progress

especially as soon as you get into that
hello rely areas to demonstrate the prime just to skyrocket
we're hearing
uh... uptown tenderloin district
is one of the oldest condenses neighborhoods in san francisco
this is where you go to buy drugs
right around here
dissociate lots of uh... aggravated assaults lots a lot of thefts
basically they're huge part of the car that happens in the
city happens just by two just viruses moderates
k
can you
diffused beam him please sirens in your neighborhood you can use them and to
find out why
if you are denied in an unfamiliar part of town deconcini and that was streets
to avoid
if the neighbor gets bergen and you can see isn't the one off why has there been
a spike in logan crime
you can use their neighborhood and a word about its safety
the fact that we have the ability to turn off all the nighttime in the middle
of the day crimes and show you just the things that are happening during the
commute
is a statistical operation
but i think to people that are interacting with the thing it feels very
much more like they're just sort of browsing the website or shopping on
amazon there their looking at data and they don't realize they're doing
statistics
what's most exciting for me
is that public statistics is making citizen
powerful
and the authorities moral compass
we have community meetings typically use a tent
and what citizens are now doing are bringing printouts of the maps which
show where crimes are taking place and they're demanding services from the
police department and the police department is now having to change how
they police
how they provide policing services
highs and the date is showing what is working and what isn't
people in san francisco roadster using public data to max social inequalities
and see how to improve society
possibilities parts and
i think ur dream
government data analysis project would really be focused on life information on
stuff that was being reported and pushed out of the world over the internet as it
was happening you know trash pickups traffic accidents pluses
through the kind of staffs gathering power of the internet it's possible to
really begin to see that the workings of the city's displayed as a unified in
advance
that's why we are heading
towards the world on fri data for the former statistical insights that come

that we've come about life's account be bad for you
maybe it's jeans
maybe people would genetically predisposed to get lung cancer are also
genetically predisposed to smoke
maybe it's not the smoking maybe its air pollution
that smokers are somehow more exposed to air pollution non-smokers
maybe it's not
smoking maybe it's public

eventually he not only showed a correlation between smoking and lung
cancer platforms to a correlation between stopping smoking and reducing
the risk
this messiahs at its best
what correlations do not replace
he's human sort
good think about what it means

there's just so much information on the internet you can help

those rules are helpful

all the time ten the insight using statistical machine translation
is saying wealthy gotta have all these exceptions anyways maybe you can get by
without having its wheels maybe he can treat everything as an exception nasa
says we want to
but the computer is doing when when he's learning how to translate is too low
in correlations between boats and correlations between phrases so we'd be
we feed this system very large amounts of data
and then the system is seeing that uh... certain good research the phrase
correlates very often to the other language

needed is basically knowledge of statistics knowledge of computer science
that knowledge of infrastructure to bolt those very large computational systems

one other exciting possibilities is combining machine translation technology
with the speech recognition technology
now both of these are statistical in nature them
machine translation relies on the statistics
of mapping from one language to another
personally speech recognition relies on the statistics of matt mapping from a
sound form to the words
when we put them together
now we have the capability of having instant conversation between two people
that don't speak a common lecture that uh... i can talk to you in my language
you hear me in your language and you can answer back and in real time you can
make that translation
can bring to get people together and allow them to speak

for statistical actions which we proved disprove or even suggested new theories
so we have decided it galaxies grounding becomes florence county cities like the
one we live in a teammate
uh... not all at once we're not smoothly specter five continuously
incorporating beasley cannibalizing
of smaller galaxies be dissolved and then they become part of under the
guidance systems
is a startling idea and you still need to is the evidence to support
groups of stars that came from cannibalized galaxies stunned often
assume they kept
artistically different prabhat the stars because they move acted different
each day despite
when one of these distribution graphs
means professional policy
has found a group of stars or travelling in a different way to the list
error that tell-tale patterns she's looking for
the evidence is accumulating
uh... this really is how galaxies girl born in portland int l tells his ground
and so this is an important part of of understanding how galaxies form not only
are posted every gals
more database the more discoveries can be made
and the technology is getting better all the
the next big survey telescope starts at seventeen twenty fifty
do you still need docs
slowed mistaken eighty years still covered one quarter of the night sky
the new tenants
with gandhi and tires scott
in even greater to resolution
every three days
the foster mom something still we have today
allows researchers inform sorts of fields
test this theory is on the previously i mean
mentioned in this case
but more than this it's many even change that
condiment in ways insist
with the power of today's computers up
plied to all these things too
and she was might even able to try to convince
potentially profoundly in
portant
potential and the significance
princeton science person even the most exciting
waste
the potential to transform officer powell scientist do science but even
more sciences possible on what will come with a constellation court
both house and she's done for the war science as possible discreetly
compensation
many of the dynamics of the natural world nike interplay between the rain
forest and the atmosphere are still complex but we don't answer the agreed
on the staff
now computers are generating literally tens of thousands of different
simulations the hoa fees biological systems might work dislike creating
thousands of a hypothetical part of the world's each and every one of the
simulations his analyzed with statistics to see if any part of good match will
report is observed in nature
the computers can now put domestic degenerate
and discard hypothesis
with scarcely humans
east new application six six
often divided for future science
is creating a new
paradigm if you like
in science midway between conducive names
which is increasingly
between my country rises
data centric or data driven
ryland being
hypothesis driven or experiment retreat
so is exciting times in terms of the science in terms of that
computations
and in terms of the statistics
now we thought that sounds a bit abstract inferior to continue
how about one final frontier
good statistics even make sense of your feelings
in california
wariness one computer scientist is harvesting the internet to try to do you
find the patterns alvaro innermost thoughts and emotions
well this is the madness with madison
represents a skyscraper views the world
each of these brightly colored dots
is an individual feelings
expressed by someone out there
blog artery
and when you click on a diet explodes
to have revealed the underlying feelings doctors
this is what people say they're feeling
batter
well
so every minute we feel fine calls the world's blogs
case all the sentences that start with the words aren't feeling feel
interest them in the database
we collect all the feelings
and week at the most common
they're better
the same
lecture
sorry
and we can take a look at anyone feeling in analyzing
right now a lot of people are feeling happy
we can take a look at all the people who are happy
and breakdown by age gender or location
says bloggers have public profiles we have that information and so we can ask
questions like
are women happier than men
isn't happy with that the united states
we find that as people get older
make you happier
and moreover we find that
for younger people
this as the happiness
more with exciting
and as people get water
this essay happiness more peaceful
and we also find that women feel love tomorrow
also more guilty
moments could more often than women
about someone
as people even more and more of their lives on line
really behind digital traces
and with these digital traces
became deeply into the statistic re-energize
what it means to be sure
so where does all of this leave office
we generate i mean mention of the quantities of data about everything you
can think of
analyzing to review the at it's
amount
not only expert but all of us
understand the stories in the mail
instead of being led astray by prejudice with statistics at our fingertips
alliance can be opened for a fact based you whatever
more than every before we can become all sorts of are all the best it's pretty
exciting isn't it
stay here
the with
he indeed
