BBA301 Rev11AN Topic 2. Statisticians and researchers encounter many ethical issues on their jobs. When working in collaboration with other scientists, a statistician might feel pressure to produce the “expected results” even when the data are inconclusive. Suggest some good strategies for handling the pressure. Human nature dictates a desire to be correct and that may cause a person to skew the information to gain a more supportive result. One way to avoid this pitfall is to include all data, even if it is not in support of the expected results. When checking data, the mean and the medium both need to be included to determine the accuracy of the data. The mean shows a central tendency as all numbers are totaled and then divided by the total of the numbers. If there are no large variances, then the mean is an
accurate indicator of central tendency. If a large variation exists, then the mean will not be a good indicator of central tendency. The medium is not affected by large variances in data; it is a middle value of an ordered array ranked from smallest to largest giving a more accurate measure of central tendency.
Another method would be to check the standard deviation and variance. The standard deviation and variance measure the average scatter around the mean and show how larger values fluctuate above it and smaller values fluctuate below it. These statistics give a spread of all values and a more accurate picture of what the data declares. The best strategy is to include all data, and all charts and graphs to depict a true and accurate representation of all data. Only by including each can a truthful picture begin to emerge about the data investigated. Personal opinion and personal agendas must be left at the door before the statistician begins to evaluate the data. Fair, neutral, and objective reports should always be used to report the findings. thread ID: 1376

E­book publishers would like to know the range of their potential or existing subscribers’ age, income, educational background, and their interest and needs. Those data are important for marketing, collaboration with other publishers, further product and service design. For example, normally E­book readers are in the range of 30­40 years old, because they keen on using new
and high technologies, most of them have mobile devices; most of them are educated and have higher income, so they are willing to spend on books. This is a good selling point to attract those young, high income people.
The ratio of children and elderly subscribers are lower, because elderly do not use new and high technologies as much as young people, and children depend everything on their parents. Therefore, if an E­book publisher wishes to expend its market on those fields, it has to design a more user­friendly and easier platform for the elderly, and add more interesting and knowledgable books for children. The ways of the publisher to get information are survey, questionnaire, telephone interviews, etc. thread ID: 1637

Ethic plays an important role on official statistics because official statistics speak for the government, basically almost every citizen believes in and adept them, and they are indications for government departments and private organizations to make and implement their policies. If such data are fake, dishonest, not only they give wrong directions to the government and private organizations, but every citizen is also affected by those wrong data. This lead people in need cannot be help (because of the wrong estimate), and some people may have too much. This may also make a wrong atmosphere. History tell us that there were some provinces in some countries reported wrong statistics to the government, and the government believed the country was getting better because
policies worked, but in fact all data are fake, and the ‘prosperity’ was not real. Millions and millions of people died in hunger, but the leaders of the government still did not know.
The main ethical challenges that arise in official statistics may be the influence of big businessmen because they may not like information which is against them to be released. Those businessmen care about their interest most. Moreover, the shortage of time and manpower may affect the accuracy, but the official cannot tell the public. In order to meet the death line (because some data or indications are useless when they are expired), they may give up the accuracy.
