Document Summary
Research design: describing our sample- statistics, population- parameter, our goal is to know our population, hope our sample is representative of our population, correlational- two variables (do they have some form of relation/association, ex. Does education have to do with level of depression. Research question and hypothesis: research question to begin with, turn question into a hypothesis, test the hypothesis, need evidence to support hypothesis, this is where statistics come to play, either confirm or find alternative explanations. Sampling design: probability sampling- best way to do this, everyone has an equal chance of being selected in the population, want our sample to represent our population, convenience sampling. Example: smoking leads to lung cancer, exceptions, some people who don"t smoke don"t get lung cancer, some people who smoke don"t get lung cancer, can"t say its absolute because it does not apply to everyone, still significant! Make predictions or generalizations based on observations: 3.
