Therefore, NIS 3,000 could actually be correct, but only because a very small percentage of families have extremely high incomes that push the average up. It would be far more interesting to see the distribution of the sectors and to discover more about the distribution of income. In knowing more about poverty, not only the average income needs to be examined, but also additional data. What our poll actually told us was that here in Palestine we have a very wealthy minority and a very poor majority. Even the most scientific data should always be scrutinized.
Some concepts are very easily quantifiable, while others prove more difficult.
One of the concepts that I use quite a lot is socioeconomic status - combining income, residence, education, etc., in an index, which gives much better results than relying on the simple concept of poverty measured by level of income. Age Nominal variables serve to classify, to put things or people into different categories. Ordinal variables , meanwhile, are stronger statistically speaking than nominal variables, as they not only classify but also arrange into some kind of order. At this level it is possible not only to distinguish between different sectors of a certain population, but also to see how the members of the different sectors are ranked, i.e., lower class, middle class, upper class, etc. There is classification, but there is also order.
