Document Summary
Chapter 2: 5 tools, the experimental room has the presence of confounding variables that can affect or influence what we are testing on, say animals. He talked us through how a change in setting can influence behavior animal. He also talked about how now a computer can control many of the confounding variables but it cannot control all of them so. There is an innate and obvious need for replication of experiments. Because one trial will not always be the same: an experiment cannot always mimic the real world that well because it has even more confounding variables that sometimes we cannot always control for. So, we focus on natural observation, but we cannot establish causation. Observation bias is also a consequence of type of experimentation. Because as we get close to the thing we are observing we can possibly integer or interact with it: case study: is an in-depth investigation into one or a few individuals.
