the reaction of a schoolchild

who made that number
nám dala to číslo
important skills for life,
that we want to introduce in this century
v tomto storočí zaviesť,
more comfortable with numbers.
looking at numeracy in young people,
keď sa pozreli na matematickú gramotnosť
in the US have low numeracy.
má nízku matematickú gramotnosť.
with figures above 20 percent.
s číslami nad 20 %.
because it doesn't have to be that way.
are in single figures.
s jednociferným číslom.
problem that we want to address.
gramotnosťou, ktorý chceme napraviť.
inadvertently into one of two categories;
rozdelenie ľudí do dvoch kategórií,
with numbers, that can do numbers,
a vedia s nimi pracovať
to talk about here today
that is a false dichotomy.
tremendously high levels of numeracy
úroveň matematickej gramotnosti,
to the journey ahead.
našej cesty vpred.
we can begin that journey, for me,
ako začať túto cestu,
that statistics has got somewhat
majú niečo ako
don't particularly like,
is all about precision and certainty,
je o presnosti a určitosti,
to the world of statistics myself.
dostal až neskôr.
na bakalára,
to excel in after university,
šancí na úspech po univerzite,
and computer programming,
a programovanie počítačov.
some statistical graphics
štatistické grafy,
was actually an interesting thing?
že štatistiky sú vlastne zaujímavé?
statistics are about us.
of the word statistics,
that we live in.
we as individuals relate to our groups,
ako my-jednotlivci súvisíme so skupinami,
are at their most powerful
surveys carried out recently
1,000 adults in the UK,
dospelých v Británii
in England and Wales,
v Anglicku a Walese
of the total population, was 24.
celkovej populácie, bola 24.

ľudí v krajine sú moslimovia.
that figure to be about five.
sa hýbe okolo piatich.
between what we think, our perception,
čo si myslíme, naším pohľadom,
that misperception?
in presentations. I was referring to it.
na prezentácie. Odkazoval som na štúdiu.
in Hammersmith,
v Hammersmithe
of sixth-form girls.
zo stredoškoláčok.

they asked the Japanese,
opýtali sa Japoncov,
just over halfway.
niečo cez polovicu.
Japanese people lived in rural areas.
Japoncov býva v odľahlých oblastiach.
and surprising to some,
a pre niekoho prekvapujúce,
who have read the work
ktorí čítali napríklad
the Nobel-winning economist.
ekonóma oceneného Nobelovou cenou.
spent years researching this disjoint
strávili roky skúmaním tohto rozdielu
and the reality,
pretty poor intuitive statisticians.
dosť mizerní intuitívni štatisti.
can influence our perceptions,
ovplyvniť naše vnímanie
reporting things by exception,
ktoré robia reportáže o výnimkách
of referring to that.
to the obvious" --
to our blindness about it."
repercussions for decision making.
na tom, ako sa rozhodujeme.
while this was all going on,
kým sa toto preberalo,
globálny problém,
how well do you know your country?
ako dobre poznáte svoju krajinu.
do you know 64 million people?
64 miliónov ľudí.
I can't do that.
Ja to neviem.
this same sort of approach
v lokálnom zmysle.
in a very local sense.
založené na dátach zo sčítania ľudu
based on census data
in designing this.
nad tým veľa uvažoval.
to the widest possible range of people,
pre najširší záber ľudí,
who can get the numbers.
z 20. a 30. rokov 20. storočia.
for representing numbers
but they sit in the background.
of representing quantity
ako ukázať kvantitu
like "percentage,"
ako „percentá“,
on the left-hand side there,
na ľavej strane
we're asking you questions about
o ktorom sa pýtame otázky,
between zero and a hundred,
medzi nulou a stovkou
between zero and a hundred.
medzi nulou a stovkou.
a quick look at the quiz
rýchlo pozrieť
how many are aged under 16?
koľkí z nich majú menej ako 16 rokov?
at all, so I had a guess at this,
takže som si tu tipol
of how this quiz works.
to highlight your icons,
aby ste označili vaše ikonky
len „Odoslať“, aby ste odpovedali
between your answer and reality.
medzi vašou odpoveďou a skutočnosťou.
terrible guess: five.
dosť zlý odhad: päť.
what the average age is,
the population are younger
je polovica populácie mladšia
middle-aged to me.
ako taký stredný vek.
it's incredibly young,
je neuveriteľne mladý priemer.
of the university in this area.
univerzity v tejto oblasti.
as you go through.
keď idete ďalej.
about homeownership:
je vlastnených na hypotéku alebo pôžičku?
are owned with a mortgage or loan?
more than 50 out on the answer.
o viac ako 50 od správnej odpovede.
these questions,
when you're in a community,
to whether a population is old or young.
či je populácia stará alebo mladá.
the area, you can see it.
is much more difficult to see,
je oveľa ťažšie zbadať,
we think own their own homes.
si myslíme, že vlastní svoje domovy.
when we published this quiz,
že keď som publikoval tento kvíz,
was already a few years old.
je založený, boli už staré pár rokov.
that allow you to put in a post code
zadať poštové číslo
and not necessarily new.
a nie vyslovene nové.
what reaction we might get
akú reakciu asi dostaneme tým,
in the way that we have,
ako sme to spravili my,
that people have their own preconceptions.
že ľudia majú vlastné predpojatosti.
to bring down a statistics website
zhodiť webstránku so štatistikami
"statistics," "gov" and "UK,"
„štatistiky“, „vláda“ a „UK“,
favorite words in a URL.
ľudí čo sa týka URL.
was that the website came down
že webstránka padla
engaging with this data
o tieto údaje
a quarter of a million people
of 48 hours of launching it.
48 hodín po vydaní.
online, on social media,
online, na sociálnych sieťach,
with their misconceptions,
chybných názoroch
I couldn't have hoped for any better,
sending it to politicians.
posielať politikom.
ktoré tvrdíte, že zastupujete?
you claim to represent?
ozaj zaujímavé vidieť,
really interesting to see
would do on this quiz.
ktorým ide práca s číslami.
of England and Wales, John Pullinger,
