SCI 1101 Lecture Notes - Lecture 7: Observer-Expectancy Effect, Design Of Experiments, Qualitative Property
Document Summary
Applications of science: policy decisions and management practices, developing technology. It is an incremental approach to the truth: scientists do not simply accept conventional wisdom, they judge ideas by the strength, observational (descriptive) science- of their evidence. Information is gathered about organisms, systems, processes, etc. Here"s how scientific investigation: the scientific method- a technique for testing ideas with observations. 9-5-17 | 2: ex- flashlight doesn"t light, car won"t start, etc, the test results either support or reject the hypothesis. Understanding probability: frequent observation = high probability of truth, high probability = high certainty in science. Science studies problems methodically: almost always easier to prove a hypothesis wrong than it is to prove it true. Experimental design can reduce bias: variable- a condition that can change, dependent variable- depends on" the independent variables, the response variable, is affected by the independent variables, graphs: on the y-axis (by convention)
