20) Research Methods and Analysis

Content analysis is a research technique for the systematic, objective and quantitative description of the content of research data procured through interviews, questionnaires, schedules and other linguistic expressions, written or oral.

21) Techniques of data collection

Basic requirements for scientific data are that it should be reliable and impartial. In Sociology these conditions are hard to meet. Yet numerous methods are used to minimize errors in data. Some of the commonly used sources in collecting data are:

  • Existing materials including the official statistical record and historical and contemporary documents.

  • Social surveys through questionnaire and schedules

  • Interviewing

  • Observation- Participants and non-participant

22) Variables, sampling, hypothesis, reliability and validity.

After reviewing earlier research concerning the homeless and drawing upon the contributions of sociological theorists, the researcher may develop an intuitive guess about the relationship between mental illness and homelessness. Such a specula­tive statement about the relationship between two or more factors is called a hypothesis.

A hypothesis usually states how one aspect оf human behavior influences or affects another. These aspects or (actors are called variables. A variable is a measurable trait or characteristic that is subject to change under different conditions. Income, religion, occupation, and gender can all be variables in a study. In the hypothesis pre­sented above, there are two variables: "homeless­ness" and "mental illness."

Scientific method requires that research results be both valid and reliable. Validity refers to the degree to which a measure or scale truly reflects the phe­nomenon under study. A valid measure of work­ers' productivity would accurately indicate how much they had produced over a specified period of time. Similarly, in the study of homelessness, researchers used definitions accepted by the American Psychiatric Association and genuinely believed to describe mental illness.

Reliability refers to the extent to which a mea­sure provides consistent results. A reliable mea­sure of workers' productivity would lead to the same results even when utilized by different re­searchers.

Sampling For practical and cost reasons, it is often impossible to collect information about the entire population of people or things in which social researchers are interested. In these cases, a sample of the total is selected for study. By using specialized sampling techniques, sociolo­gists avoid the necessity of testing everyone in a popu­lation.
