How statistics can be used to MEAN more than just a MEDIAN.
INTRODUCTION
SST
Statistics is the collection, organisation and interpretation of numerical data.
Meet Goofy George…• Rather uneducated
• Makes generic comments
• Not much substance in what he says
• His statements don’t really make an impression.
How can statistics be used effectively to convey a message?
Statistics can be used to:
1. Make a stronger impact.
2. Make generalisations more factual
3. Predict trends
4. Make comparisons
POVERTY There are many people dying of hunger around the world.
POVERTY
Statistics can be used to:
1. Make a stronger impact.
2. Make generalisations more factual
3. Predict trends
4. Make comparisons
POVERTY
According to UNICEF,
25 000 children die…
…due to poverty.
Each day…

In the world,
POVERTY
there are 1 BILLION children in poverty…
Out of the 2.2 billion children in the world.
That is nearly half.
Over three billion people live on less than $2.50 a day.
This is almost half the world!
POVERTY
DEFORESTATION
We are cutting down so many trees around the world.
DEFORESTATION
Statistics can be used to:
1. Make a stronger impact.
2. Make generalisations more factual
3. Predict trends
4. Make comparisons
DEFORESTATION
13 million hectares
of the world’s forests
are being LOST each year.
The Food and Agriculture Organization of the United Nations (FAO) released its 2005 Global Forest Resources Assessment

DEFORESTATIONIn Nigeria 81% of its
original forest cover is now permanently lost
Countries like India, Mexico, Philippines, Thailand, Indonesia, Bangladesh, Myanmar, China, Sri Lanka, the Congo and Ghana have lost much more than 50% of their rainforest cover.

CLIMATE CHANGE
Hmmm… Global Warming. The Earth must be warming up!
CLIMATE CHANGE
Statistics can be used to:
1. Make a stronger impact.
2. Make generalisations more factual
3. Predict trends
4. Make comparisons
The year 1998 was the warmest on record.
The year 2002 was the 2nd warmest. The year 2003 was the 3rd

WAR and PEACE
Countries should stop fighting.
Make peace not war.
WAR and PEACEStatistics can be used to:
1. Make a stronger impact.
2. Make generalisations more factual
3. Predict trends
4. Make comparisons
WAR and PEACEUS$275 000 000 is spent for three tests of missile defence system.
This amount of money could be enough to stock 204 500 medical clinics around the world…
… for a WHOLE YEAR!!!
WAR and PEACE
US $350 000 000 is spent on
six Trident II missiles.
This amount is enough to build wells in Africa…
…to provide water to 65 million people
WAR and PEACE
US $2.1 billion is the price of just ONE stealth bomber.
WAR and PEACEThis same amount could be used to…
Immunise over 134 million children in the world…
…against diseases such as:
• Measles
• Typhoid
• Tuberculosis

IN SUMMARY…Statistics could be used to:
1. Make a stronger impact.
Each day, 25 000 children DIE due to POVERTY!
2. Make generalisations more factual.
13 million hectares of the world’s forest is LOST each year!
3. Predict trends.
The Arctic region could be ice-free by
2040!
4. Make comparisons.
The US$350 million spent on 6 missiles could
be enough to provide wells in Africa to
65 million people
