TRANSCRIPT

  • Using numbers to persuade

  • Expressing numbersRead the article 'A nation of addicts glued to the box'.

    Identify and comment on the statistics used in the article.

    Identify and comment on the language used to express the statistics in the article.

  • A nation of addicts glued to the boxIf television is truly the 'drug of the nation' then it appears that we are cripplingly addicted to it. More than half of us devote more than five hours of each and every day to getting another fix of its transmissions. We waste away 72 days each year in a flurry of nature documentaries, soapy melodrama and live sport.The survey carried out by a national building society also shows that more than a third (35%) of those asked owned two TV sets, just under a quarter (23%) had three and 6% had more than five sets.The most common activity associated with viewing is eating, with more than two-thirds of families now having their meals whilst watching TV.However, perhaps the most disturbing statistic was the indication that one in five believe that without television life would hardly be worth living.The results of the survey disturb Greg Philo of Glasgow Media Group. 'To produce this average... There must be some people watching eight, ten hours a day... If you just sit down in front of the TV you can spend hours where you've not really achieved anything. TV stops us from doing the really good things in life.'Alasdair Reisner

  • How we persuadeThink about the sentence:

    'We waste away 72 days each year in a flurry of nature documentaries, soapy melodrama and live sport.'

    What can you say about the language used?

  • How we persuadeHow else could we express '72 days'?

    What happens if we express it as;'19% of our time'?'less than a fifth of a year'?

    Can you think of other ways to express it?

  • How we persuadeWhat would happen if we expressed it like this:

    'We spend less than a fifth of our time using TV for educational, news and entertainment purposes'?

    Can you think of another way to express this sentence?

  • How we persuadeThink about the sentence:

    'The survey carried out by a national building society also shows that more than a third (35%) of those asked owned two TV sets, just under a quarter (23%) had three and 6% had more than five sets.'

    Why do you think the author has included this information? What can you say about the language used?

  • How we persuadeWhat happens to this sentence if we give exactly the same figures in a different way?

    'The survey carried out by a national building society showed that almost two-thirds of households had no TV or only one.'

    What would be the intention of stating the statistic this way?

  • Changing the tone

    Rewrite the first two sentences (from 'If television' to ' its transmissions') to give a positive view of people's TV watching habits.

  • Using statistics to convey a message

    As you can see, numbers can be expressed in a variety of ways.How we express numbers can be used to convey a message to the reader or listener.Think about different ways to express numbers for particular purposes.

  • What's the difference?Factually, there is no difference between33% of people think YOne in three people think YTwo-thirds of all people think ZMore than three out of ten people think YLess than a third of all people think YHowever, is there a difference tonally in these expressions?

  • Maximising and minimising statisticsWe can make a statistic sound a lot or sound a little depending on how we express it.In your groups, look at the statistics in the following table.How could you express them in a way that seems to you to make them sound:neutral?a lota little?

  • PercentageSuggested alternativeMake it sound a littleMake it sound a lot10%One-tenth'Only around''As much as'23%'Almost'3 in 1049% 'Almost'52%Two-thirds75%90%All

  • PercentageSuggested alternativeMake it sound a littleMake it sound a lot10%One-tenth'Only around''As much as'23%'Not even a quarter''Almost a quarter'30%3 in 10'Less than a third''As many as one in three'49%5 in 10'A minority' 'Almost a half '52%5 out of 10'Barely half''A clear majority'66%Two-thirds'As many as a third' [reference to the opposite]'Two out of every three'75%Three-quarters'A significant minority' [reference to the opposite]'It's hard to ignore the fact that three quarters'90%9 out of 10'Hardly surprising that' [make it seem too obvious to mean much]'All but'

    100%All'Of course everyone but' [make it seem too obvious to mean much]

    'It is unanimous'

  • Stating the blooming obvious...How can we minimise and cast doubt on large statistic?We can make it seem so obvious as to be worthless. Think about the following examples:Of course everyone would agree with X: its a bit like agreeing that air is good for you...So what if 100% of the population believe in Y: is what is popular always what it right?

  • Lies, damned lies and statistics(http://en.wikipedia.org/wiki/Lies,_damned_lies,_and_statistics)The same statistics can be used for very different purposes, depending on the purpose of the reader or speaker.Look at the following table, which shows how the rate of smoking and the incidence of lung cancer has changed between 1948 and 2009.What conclusions would you draw from these figures?

  • Source: Cancer Research UK http://info.cancerresearchuk.org/cancerstats/types/lung/smoking/#cancer

  • The Clean Air GroupThe Clean Air Group is a pressure group which campaigns for increased cigarette taxes and more smoke-free zones, with a view to an eventual ban on smoking.Imagine the group has just received this information from Cancer Research UK.Write a brief press release commenting on what the figures reveal.

  • Free Smokers Now!Free Smokers Now! is a campaign group which advocates personal choice in smoking and the repeal of anti-smoking legislation which limits smokers' rights.Imagine the group has just received this information from Cancer Research UK.Write a brief press release commenting on what the figures reveal.

  • Migration: pressure groupsHands across Borders: A humanitarian body which promotes sensitivity towards immigrant issues and campaigns for greater freedom to come to the UK.Border Watch: A think-tank which examines migration figures and advises on policy, particularly with a view to implementing stricter immigration controls.Imagine these groups have just received the following information from the UK government.Write a brief press release for each group, commenting on what the figures reveal.

  • Self / Peer EvaluationWrite down in bullet points how comfortable you feel now about the use of statistics in persuasive writing. You may wish to identifyWhat you found easy or difficult about these tasks;What ways you think you can use statistics that you didn't know before;What questions you would like answered to be able to use statistics more effectively. Submit your bullet points to your teacher / share them with your peers.

    *****************Suggested exemplar: The Clean Air group welcomes these latest figures which clearly show that the UK is turning its back on the disgusting habit of smoking. It is staggering to think that, in 1948, 4 out of 10 women and almost 7 out of 10 men smoked. Thankfully, thanks to decades of campaigning, the public now realises the dangers it faces, and a paltry 20% now indulge in this fatal addiction. As a result, we have seen a satisfying reduction in the incidence of lung cancer, with deaths per thousand tumbling by a quarter. However, this is still too high, and we must not rest until this curse on the health of our nation is eradicated completely.

    *Suggested exemplar: Figures released by Cancer Research UK seem to confirm what our group has always said: that the link betwee
