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!

DEFORESTATION

We are cutting down so many trees around the world.

DEFORESTATION

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.

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
