Research in music education
A "survey" is a systematic method of collecting information on one or more variables. An example of a survey study is a 1998 study by Gillespie and Hamann. The purpose of the study was to gather descriptive information about orchestra programs that can be used as baseline data when considering the needs of school string programs. The findings indicated a continued enrollment increase in school orchestras in the 1990s although the number of orchestra teachers remained stable, and that larger schools are more likely to offer orchestra instruction. The impact of the study was the recommendation that school systems should provide larger, more adequate teaching facilities and that universities and string teachers should emphasize strategies for teaching larger string classes in their teacher preparation programs.
Survey methodology
A single survey is made of at least a sample (or full population in the case of a census), a method of data collection (e.g., a questionnaire) and individual questions or items that become data that can be analyzed statistically. A single survey may focus on different types of topics such as preferences (e.g., for a presidential candidate), opinions (e.g., should abortion be legal?), behavior (smoking and alcohol use), or factual information (e.g., income), depending on its purpose. Since survey research is almost always based on a sample of the population, the success of the research is dependent on the representativeness of the sample with respect to a target population of interest to the researcher. That target population can range from the general population of a given country to specific groups of people within that country, to a membership list of a professional organization, or list of students enrolled in a school system (see also sampling (statistics) and survey sampling). The persons replying to a survey are called respondents, and depending on the questions asked their answers may represent themselves as individuals, their households, employers, or other organization they represent.
