To obtain the most benefit from studying this paper we need to have a basic understanding of the way researchers gather information from populations and apply certain statistical techniques in order to come to acceptable conclusions. As a researcher we may be given a task of measuring some characteristic of our
community such as the level of expenditure on transport infrastructure, the density of population in various parts of the city or the level of interest in the local development of sporting facilities.
The other data form we use is the qualitative variable. The measure we use here is not numerical but a categorical one. A common example is the use of a YES/NO response. Other examples include occupation of the respondent, type of building classified by its outer cladding or make of motor vehicle.
