A clearly defined research question allows us to formulate hypotheses that propose possible answers to that question. From these hypotheses, we can then derive specific, unambiguous predictions that allow us to test their validity with empirical data. Hypotheses and predictions serve to narrow down the infinite possibilities for data collection and determine the data we need to collect. In this chapter I cover formulating hypotheses and predictions, then explain that we often use proxies to test predictions and how practical constraints influence our thinking.
