Data Collection Methods: Descriptive Studies Descriptive studies make use of two primary sorts of data collection: cross-sectional studies and longitudinal studies. The cross-sectional study attempts to give a snapshot of data at a certain moment in time -- variables in a cross-sectional study are measured only once. The longitudinal study, on the other hand, involves a fixed, relatively stable sample measured repeatedly over time. In both cases, methods used might include mail, online or in-person surveys or interviews. Data Collection Methods: Causal Studies Case studies likewise make use of two primary sorts of data collection: laboratory experiments and field experiments. Laboratory experiments are conducted in artificial environments which allow researchers to carefully control exactly which variables are manipulated while keeping other factors constant. Field experiments are conducted "in the field," in a natural or realistic environment. Field experiments allow researchers to test how their hypotheses apply to the "real world." However, it is often impossible for researchers to control for all possible variables in field experiments, making it harder for researchers to say with confidence exactly what produced a given effect.
