Intro to Statistics 9/7 Statistics is the science of… Collecting Describing Organizing Summarizing And interpreting data! Important to note: like how analogies must use logic in order to make successful comparisons, problems in statistics must be related. The data has to be compared to something in order to be meaningful. You can use statistics to… Prove your ideas with facts Predict outcomes Vocab: Fact= observable data Theory= an understanding that helps lead us to the facts Population= all of the individuals of a group being studied Sample= a subset of the population which (hopefully) is representative of the population as a whole Convenience sample-when the researcher chooses participants based on convenience. (i.e students, friends, etc) Random sample- when the researcher chooses participants in a completely random fashion. Representative sample- when the researcher chooses participants in a way that reflects the population as a whole. Which one do you think works the best… Parameter= broader than a statistic. A parameter is always in regards to an entire population. Statistic= differs from a parameter in that it only describes data taken from a sample. Descriptive Statistics- allows us to describe and visualize the data, as in graphically Inferential Statistics- allows us to infer truths about a population based on data gathered from a sample
