Document Summary
Pol242 may 15: the fundamentals of research design for an experimental study. The way we structure an idea and based on that, we try to collect data to test for correlations/causal relationships between variables. It is a set of procedures for testing a hypothesis about a relationship. This research design involves understanding basic concepts: If you see that the independent variable changes or influences. What the effect is, however, you have to find out. We aim to generalize our findings because we want our results to go beyond our study. The effect of cutting off the leg would be the difference in height before and after. In other words, y would be both the height before and then the height after. Suppose we wanted to determine the effect of cutting off a table"s leg on its height. off the legs. The effect would be the difference in height so it would be y" before y" after.
