QUESTIONNAIRESA、ADVANTAGES & DISADVANTAGES

Every coin has two sides and questionnaires are no different. With questionnaires, the advantages outweigh the disadvantages.

ADVANTAGES OF QUESTIONNAIRES

Compared to face-to-face interviews, questionnaires are cheaper for

collecting data from a large number of respondents. Also, questionnaires are easy to analyze, and computer software can easily complete data entry and make tables for nearly all surveys. Questionnaires are familiar to most people as nearly everyone has had some experience completing one. Questionnaires reduce bias when there are no clues to affect the respondents.

DISADVANTAGES OF QUESTIONNAIRES

One main disadvantage of questionnaires is the possibility of low response rates which reduces our confidence in the results. Another disadvantage is they provide little flexibility for the respondents. What’s more, many times the respondent is not the same person you sent the

questionnaire to. Finally, questionnaires are not suitable for some people. For example, a survey to a group of poorly educated people might not work because of reading problems.

n. It has been argued that the supply of good land is limited. To feed a large population, inferior land must be cultivated and the good land worked intensively. Thus each person produced less and this means a lower average income that could be obtained with a small population. Other economists have argued that a large population gives more scope for specialization and the development of facilities such as ports, roads and railways, which are not likely to be built unless there is a big demand to justify them.

One of the difficulties on carrying out a world-wide birth control program lies in the fact that official attitudes to population growth vary from country to country, depending on the level of industrial development and the availability of food and raw materials. In the developing country where a vastly expanded population is pressing hard upon the limits of food, space and natural resources, it will be first concern of government to place a limit on the birthrate, whatever the consequences may be. In a highly industrialized society the problem may be more complex. A decreasing birthrate may lead to unemployment because it results in a declining market for manufactured goods. When the pressure of population on housing declines, prices also decline and the building industry is weakened. Faced with considerations such as these, the government of a developed country may well prefer to see a slowly increasing population, rather than one which is stable of declines.

Small population may mean ______.

A．higher productlvity, but a lower average income

B．lower productivity, but a higher average income

C．lower productivity and a lower average income

D．higher productivity and a higher average income
