Document Summary
Empirical data based objectively on quantifiable observations. Should be able to repeat outcomes confirms findings of research. Replicate w/ extension scientists generate new information as they confirm prev findings. Change errors, faulty reasoning, and conclusions when proved wrong. Manipulate factors of interest to determine effects. Experiment performed when directly manipulating factor that is central focus of research. Attempt to determine cause and effect relations that exist in nature. Changes in dv result from manipulation of iv. Factors other than iv that can influence dv and change results. They are unwanted and we have no way of knowing if they are cause. Prediction about relation that exists b/w iv and dv. Should use synthetic statements when forming research hyp. Principle of falsifiability when experiment doesn"t result in what you planned, hyp = false. Cannot prove that your research hyp is absolutely true. Directional research hypothesis specify outcome of the experiment: more likely to find statistically significant result.
