QUESTIONS
TO SPOT A
BAD
STATISTIC
INSIGHTS: “3 ways to spot a bad
statistic”-
Mona Chalabi at TEDNYC
INSIGHT #1.
Statistics are very
crucial for a society.
We need stats to make
sense of society as a whole,
in order to move beyond
emotional anecdotes and
measure progress in an
way.
1.
• How can a government create fair policies if they
can't measure current levels of unfairness?
2.
• How can we legislate on health care if we don't
have good data on health or poverty?
3.
• How can we have public debate about
immigration if we can't at least agree on how many
people are entering and leaving the country?
• INSIGHT #2.
Questions that
will help you be
able to spot
some bad
statistics.
Ques. #1 Can you see uncertainty?
1.
• A lot of data visualizations will overstate
certainty, and it works - these charts can
numb our brains to criticism.
2.
• When you hear a statistic, you might feel
skeptical.
3.
• As soon as it's buried in a chart, it feels
like some kind of objective science, and
it's not.
Move from a
single
independent
variable and
focus on the
other variables
as well.
Ques. #2: Can I see
myself in the data?
Data must exhibit, how it
relates to everyday lives
of common people.
The point of asking where
you fit in is to get as much
context as possible.
Ques. #3. How was
the data collected?
It's also worth
asking how the
survey was carried
out.
Employing the Insights into the life of a
Manager.
Making Better Decisions
Better the
Quality of
the Statistics
Better the
Decisions
by a
company
Better the
Understandin
g of the
information
So, how do you question government statistics?
• You just keep checking everything.
• Find out how they collected the numbers.
• Find out if you're seeing everything on the chart you need
to see.
• But don't give up on the numbers altogether, because if
you do, we'll be making public policy decisions in the
dark, using nothing but private interests to guide us.
Thank
You!
