返回 目录 Unit 8 Science and Technology Text A Translation Statistics is an indispensable part in modern news or comments to show credibility. However, do statistics necessarily mean truth? TEXT A

返回 目录 Unit 8 Science and Technology Text A Translation Truth and Statistics 1 We are attacked by statistics every day –from opinion polls to government figures on crime, from measures of what is a healthy weight should be, to product claims in advertising: “eight out of ten owners said their cats preferred it”, and so on! What is more, where there is a statistic, there is also bound to be an argument with counter statistics.

返回 目录 Unit 8 Science and Technology Text A Translation 2 Faced with this storm of figures, it is easy to run and hide or alternatively to simply respond with critical expressions. However, both responses are probably born out of a fear of Maths. Actually, statistics is simply a way of interpreting data.

返回 目录 Unit 8 Science and Technology Text A Translation Even so, different interpretations have lesser or greater validity. A survey with a sample of 5, 000 chosen at random will be more valid than if you just asked five friends who think the same way as you. A study which has been checked by other experts is more likely to be accurate than one which is published anonymously on the Internet. Without any truth in statistics, we have no science, no policy developments, no progress. So every citizen is supposed to be equipped with a basic understanding of how statistics work and a certain doubt which looks for underlying problems with the data and research we are presented with. 3

返回 目录 Unit 8 Science and Technology Text A Translation For example, differences between absolute and relative figures can be made to work for what you want. Company A could report it had increased production 100% more than a rival, by comparing relative increases. Company A may have started producing 1, 000 TVs and increased it to 1, 400 (40%) while Company B started from 10, 000 and increased it to 12, 000 (only 20%). Furthermore, the absolute increase may hide inefficiencies, because Company A employed more people to get the increase whereas Company B achieved it while reducing staff. 4

返回 目录 Unit 8 Science and Technology Text A Translation In the case of probabilities, we also need to ask whether variables are independent of each other and the sample group. For example, the chances of being involved in a train crash are the same each time you board a train: in terms of the passenger, it is essentially a random event, like winning the lottery. So experiencing a train accident will not increase your risk the next time you take the train. The probability of having a heart attack, however, may be dependent on various things including whether you have had one before. If you have, the risk of another is very 5 much increased.

返回 目录 Unit 8 Science and Technology Text A Translation Finally, once you have checked the figures, you still need to assess the conclusions drawn: the fact that TV sales increased in line with crime does not prove that one affected the other. The choice of statistics and conclusions may be the result of selfinterest if the researcher is not independent. 6

返回 目录 Unit 8 Science and Technology Text B Translation With the development of science and technology, new forms of entertainment, like video gaming, start to appear. What are their effects on our lives? TEXT A

返回 目录 Unit 8 Science and Technology Text B Translation Not the End of the World 1 The popular media has long portrayed the players of video games as socially inadequate, under-achieving young males. They claim that those young people are doomed to remain glued to a screen for much of their waking lives, without the prospect of any kind of career or normal human relationship. Moreover, some journalists are keen to assume a strong correlation between violent or criminal tendencies and familiarity with shooting games. What is interesting to know is that research by the wellregarded sociologists Ian Macquarie and Karina Rylands (published 2009), has proved that social and even genetic factors have much more of an influence.

返回 目录 Unit 8 Science and Technology Text B Translation 2 The truth is that the appeal of gaming is not limited to those of a particular gender or age. It’s a popular form of entertainment and is a far more mentally stimulating way of spending your time than watching television, which, funnily enough, was also accused of being “the downfall of culture” when it first began appearing in homes. Indeed, to deny even infants access to video games is to hold them back. It has always been the case that game play engages developing minds in the learning process, and modern technology offers exciting new opportunities in this regard.

返回 目录 Unit 8 Science and Technology Text B Translation 3 There are some areas of published research which some journalists chose to neglect, but are nevertheless widely available to people who take a genuine interest in their children’s social and intellectual development. First of all, scientists from the University of Wisconsin have established in a key study that traditional video games actually sharpen the mind, and not only in the case of young people. It has been shown that, by regularly engaging in this type of activity, the elderly are more likely to retain skills such as the ability to reason and multi-task into later life. Surely this is a highly desirable benefit, which could even lead to savings in health care.

返回 目录 Unit 8 Science and Technology Text B Translation 4 It may also be surprising to know that, contrary to the claims that video gaming automatically leads to childhood obesity, games are now increasingly being used for fitness training in the USA. In fact West Virginia has provided such a game to all the middle schools under its authority. People run, walk, jump, squat and dance on special mats, following instructions on a screen. When the weather doesn’t permit an outdoor physical education programme, children can still take indoor exercise using these “active” games, increasing their range of options.

返回 目录 Unit 8 Science and Technology Text B Translation 5 This does not mean that gaming has no serious side effects, but enjoyed in moderation, the advantages are numerous. The one-sided view of video gaming is simply frustrating.

返回 目录 Unit 8 Science and Technology Text B I. Check whether the following statements are true (T) or false (F) 1. The popular media has made it clear that there is no link between video games and aggressive behaviour. (F) 2. Only lonely men take a genuine interest in gaming. (F) 3. It’s almost impossible for parents to get access to research about the benefits of video games. (T) 4. Games can help people to preserve their mental faculties for longer. (F) 5. In West Virginia, video games have replaced outdoor sports in most middle schools.
