Measurement in social science is a process. It occurs at multiple stages of a research project: in the planning stages, in the data collection stage, and sometimes even in the analysis stage. Recall that previously we defined measurement as the process by which we describe and ascribe meaning to the key facts, concepts, or other phenomena that we are investigating. Once we’ve identified a research question, we begin to think about what some of the key ideas are that we hope to learn from our project. In describing those key ideas, we begin the measurement process.
Let’s say that our research question is the following: How do new college students cope with the adjustment to college? In order to answer this question, we’ll need some idea about what coping means. We may come up with an idea about what coping means early in the research process, as we begin to think about what to look for (or observe) in our data-collection phase. Once we’ve collected data on coping, we also have to decide how to report on the topic. Perhaps, for example, there are different types or dimensions of coping, some of which lead to more successful adjustment than others. However we decide to proceed, and whatever we decide to report, the point is that measurement is important at each of these phases.
As the preceding paragraph demonstrates, measurement is a process in part because it occurs at multiple stages of conducting research. We could also think of measurement as a process because of the fact that measurement in itself involves multiple stages. From identifying one’s key terms to defining them to figuring out how to observe them and how to know if our observations are any good, there are multiple steps involved in the measurement process. An additional step in the measurement process involves deciding what elements one’s measures contain. A measure’s elements might be very straightforward and clear, particularly if they are directly observable. Other measures are more complex and might require the researcher to account for different themes or types. These sorts of complexities require paying careful attention to a concept’s level of measurement and its dimensions. We’ll explore these complexities in greater depth at the end of this chapter, but first let’s look more closely at the early steps involved in the measurement process.
KEY TAKEAWAYS
- Measurement is the process by which we describe and ascribe meaning to the key facts, concepts, or other phenomena that we are investigating.
- Kaplan identified three categories of things that social scientists measure including observational terms, indirect observables, and constructs.
- Measurement occurs at all stages of research.
EXERCISE
- See if you can come up with one example of each of the following: an observational term, an indirect observable, and a construct. How might you measure each?
