MEASURES OF DISPERSION They answer the question: How spread out is the data? Is it mostly concentrated around the center, or spread out over a large range? Standard deviation, variance, range. MEASURES OF POSITION They answer the question: How is one individual entry positioned with respect to all the others? Percentiles, deciles, quartiles. MEASURES OF ASSOCIATION They answer the question: If we know the score of an individual on one variable, to what extent can we successfully predict how he is likely to score on the other variable?
Determine a research design. Collect the data. Analyze the data. Interpret the results. Draw general conclusions and raise further questions. We will now examine each of these steps in some detail. 1. The General Research Question This is the starting point. In order to start a research project, you must first determine a general theme and a general research question. The general research question must be chosen so that it is relevant either from some theoretical perspective or from the point of view of its concrete applications.
Survey designs, 2. experimental designs, and 3. archival research designs. Other research designs are more suitable for qualitative data and we will not discuss them now. SURVEYS Surveys consist in asking a large number of people some specific questions, or in collecting data about a large number of statistical units1. When you conduct a survey, you construct a questionnaire (that is, a list of all the questions for which you are seeking answers), you determine the sample or population on which you want to conduct it, you then fill the questionnaires either by direct interviews or by asking people in your sample to fill the questionnaires themselves, or by consulting some appropriate archive.
