Why Statistics? STATISTICS = EVIDENCE Statistics is about collecting (“gathering”) and analyzing data: ◦ Design: planning how to gather data for a research study to investigate questions of interest; a poor design cannot be fixed afterwards, no matter what you do ◦ Or how much data you collect, or how fancy your analyses are, or how unique your dataset is, etc. ◦ Description: summarize the data obtained in the study ◦ Inference: make predictions (“inferences”) based on the collected data (and making some assumptions about them) to deal with uncertainty Statistics is about Model Building 𝑜𝑢𝑡𝑐𝑜𝑚𝑒𝑖 = 𝑚𝑜𝑑𝑒𝑙 + 𝑒𝑟𝑟𝑜𝑟𝑖 The outcome (or score) of the ith unit (a person, a company, etc.) is a function of your proposed model (that applies to all units) plus some error that will be different for each unit ◦ Data we observed can be predicted from a model we choose to fit plus some error ◦ The “model” will vary in shape, complexity, etc. but the logic is the same ◦ Over time, we would like to progressively build better fitting models; that is, models that explain more and more of an outcome of interest ◦ Model = ‘predicting an outcome from some variables’ Types of Research Conceptual: Theory Conceptual: Theory Conceptual: Integrative Reviews Conceptual: Integrative Reviews Conceptual: Methodological Qualitative: Ethnography Qualitative: Case Study Qualitative: Case Study Flipping Coins Quantitative: “Experiments” Quantitative: “Experiments” Quantitative: Surveys Quantitative: Longitudinal Quantitative: Meta-Analytical The quantitative research process Results in a typical structure for quantitative research studies
