A case study focuses on a single individual, a small group of people, or occasionally a single event. You'll be conducting qualitative research to find specific details and descriptions of how your subject is affected. 1  For example, a medical case study might study how a single patient is affected by an injury.ou may be asked to prove that the case study does no harm to its participants. 1  Follow this step even if you are conducting a retrospective case study. 2  In some cases, publishing a new interpretation can cause harm to the participants in the original study.
Formula or Equation Note. The incremental capital output ratio (ICOR) is defined as the ratio between investment in some previous period(s) and the growth in output in the subsequent period.Needless to say, ICOR calculation is based on constant price data.ormula or Equation Note.

In principle, any input can be used in the denominator of the productivity ratio. Thus, one can speak of the productivity of land, labour, capital, or subcategories of any of these factors of production. One may also speak of the productivity of a certain type of fuel or raw material or may combine inputs to determine the productivity of labour and capital together or of all factors combined. The latter type of ratio is called âtotal factorâ or âmultifactorâ productivity, and changes in it over time reflect the net saving of inputs per unit of output and thus increases in productive efficiency.
