(a)
Interpretation: The statement, a patient has high fever and a rash on her backshould be classified as an observation, a hypothesis, an experiment of a conclusion.
Concept Introduction: In research, observation must be the first step. This step decides the direction of research. The hypothesis can be defined as the thought that one assumes to be found or it can be the prediction of specific belief about the scientific idea. An experiment is the research based on scientific ways and methods that gives final conclusion of the experiment.
(b)
Interpretation: The statement, a nurse tells a patient that her baby who gets sick after drinking milk may be lactose intolerantshould be classified as an observation, a hypothesis, an experiment of a conclusion.
Concept Introduction: In research, observation must be the first step. This step decides the direction of research. The hypothesis can be defined as the thought that one assumes to be found or it can be the prediction of specific belief about the scientific idea. An experiment is the research based on scientific ways and methods that gives final conclusion of the experiment.
(c)
Interpretation: The statement, numerous studies have shown that omega-3 fatty acids lower triglyceride levelshould be classified as an observation, a hypothesis, an experiment of a conclusion.
Concept Introduction: In research, observation must be the first step. This step decides the direction of research. The hypothesis can be defined as the thought that one assumes to be found or it can be the prediction of specific belief about the scientific idea.
