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.
Ease of doing business index
The report is above all, a benchmark study of regulation. The survey consists of a questionnaire designed by the "Doing Business" team with the assistance of academic advisers. The questionnaire centers on a simple business case that ensures comparability across economies and over time. The survey also bases assumptions on the legal form of the business, size, location, and nature of its operations. The ease of doing business index is meant to measure regulations directly affecting businesses and does not directly measure more general conditions such as a nation's proximity to large markets, quality of infrastructure, inflation, or crime.
