Document Summary
Empirical research: must be countable, seeable, and recordable. Based on a direct/indirect observation or experience. Predictive research: gathering data and making a prediction. Chinese traditional doctor trying to research or treat alzheimer. Chinese doctor applying traditional medicine to women with menstrual problems. Ethnographic- looking at a group of people instead of individuals. Trying to figure out what"s going on at a group level. Usually has a control group and a treatment group. Try something with one group, but not the other. Ex. reduce smoke in one home, but leave smoke in another. Ethical and practical hurdles with observation and experimental methods. Reliability: other scientists can do the same research and get the same results. Validity: the experiment actually measures what it was supposed to. Sampling- should be representative of the population. Sampling bias- most studies depend on volunteers.
