Document Summary
Science as one form of truth logical system that bases knowledge on direct systematic observation stands apart from faith, belief, or conventional wisdom rests on empirical evidence: information we can verify with our senses. Reliability, validity, replication reliability- consistency in measurement- every time it is measured the same way validity- measuring what you intend to measure replication- repetition of research by other investigators complete replication di cult to achieve. Types of variables independent variable- variable that causes the change dependent variable- variable that changes and is a ected by the independent variable. Causal relationship cause + e ect requires demonstrated correlation; an independent variable occurs before the dependent variable; no evidence that a third variable could be causing a spurious correlation between the two. Population + sample population- the people who are the focus of the research sample- the part of the population that is supposed to represent the population as a whole random sampling.
