Question

In which stages of the data investigation cycle would you consider (a) level of measurement and (b) choice of research design? Explain. (open-ended question)

Answer 1

As we know there are several stages of the data investigation cycle such as set up hypotheses, planning of the investigation, the process of data collection, statistical data analysis, corrective actions, and reporting of the results for data investigation. We need to analyze different types of variables during the data investigation. During the stage of statistical data analysis, we need to consider the level of measurement of each variable, because our actions would depend on the level of measurements. For different levels of measurement, we would change the statistical methods associated with the investigation. We will consider the choice of research design during the planning of the investigation. It is very important to select the specific type of research design for the specific type of research scenario. There are several types of research designs are available such as case-study, observational study, field experiment, quasi-experiment, etc.
