With this in mind, a common mistake made by researchers is that they begin their investigations far too early, before they have thought critically about what information is required to address the research problem.A researcher using a case study design can apply a variety of methodologies and rely on a variety of sources to investigate a research problem.
Measurements are taken on each variable over two or more distinct time periods.A broader, more complex research problem can be investigated because the researcher is not constrained by using only one method.Using a quantitative framework, a sequential study generally utilizes sampling techniques to gather data and applying statistical methods to analze the data.Empirical association -- a valid conclusion is based on finding an association between the independent variable and the dependent variable.
The use of cohorts is often mandatory because a randomized control study may be unethical.You will see that each design takes a different approach in.An exploratory design is conducted about a research problem when there are few or no earlier studies to refer to or rely upon to predict an outcome.Due to the repetitive nature of this research design, minor changes and adjustments can be done during the initial parts of the study to correct and hone the research method.
