Document Summary
Laws as universal generalizations: generalizations point to causation and laws and therefore supports deep exploration o. Science affords intervention in reality, i. e. , power to change things o. An integral feature of scientific practice is the use of careful observation, measurement, and manipulation of variables. A variable is the object concept or event being measured. Research: measurements that are objective, valid, and reliable, techniques to reduce bias, made public, can be replicated. To check for consistency and coherence, we need to be able to compare diff results and get same measurements: operational definition (means we"ll speak the same language) Statements that describe the procedures or operations and specific measures that are used to record observations. Consider you wanted to study shyness causing loneliness. If diff researchers use diff definitions, they could come to exact opposite conclusions about the hypothesis. Shyness: infrequent communication or contact with others (wants to connect)
