Analyticsturning information into insight and developing conclusive fact-based strategies to gain a competitive edge Analytics ecompasses- extensive use of data, statistical, and quantitative analysis and fact-based decisions

• stats or study of data analysis
• management science or study of modal building,

optimization, and decision making Descriptive/ Diagnostic Analystics encompasses the set of techniques that describes what has happened in the past Descriptive Analytics includes graphical anaylsis, discovery of patterns Graphical Analysishistograms, run chart, scatter diagrams, pareto chart Discovery of Patterssums, averages, percentages Predictive Analyticstechniques that use models constructed from past data to predict the future or ascertain the impact of one variable oon another Predictive Analytics toolsmodels or the use of simulation Modelstime analysis (trend), regressions, statistical quality control Perspective Analyticsdecision models that indicate the best course of action to take

Perspective Analytics tools optimization models, simulation, and decision making Optimization Modelslinear programming Big Datarefers to both structured and unstructured data in large volumes The Davenport-Kim 3 stage Model maps out an approach to quantitative analysis frame the question - solving the problem - communicating results

• Levels of Measurementnominal, ordinal, interval, ration

Categorical DiscreteNominal and Ordinal Nomicallowest level of measurement; labels/categories that only contain 2 combonations (ex. pass/fail; cereal brand, etc.) Ordinalplaces data objects in order according to some quality; typically measures concepts like satisfaction ( ex. ranking colleges, cities) Numerical ContinuousInterval and ration Intervalhas an order and all objects are equal and the inbetween matters. They do not have a true zero.(ex. temperature, sizes) Rationumbers can be compared as multiples or ratios; has a true zero (stock, prices, income)

Qualitative researchexploratory; data not characterized by numbers (textural, visual, or oral) Quantitative Researchquantifies the problem using numerical data; measurements and analytics Qualitative Designqualitative research and quantitative research Quantitative Designexperimental units, treatments, and respones Experimental Unitesthe subject or objects that are being observed Treatmentsthis is the procedures that are being applied to each subject Responsesthe effects of the experimental design Data Managementrefers to cleaning and organizing a data set that has been collected. It is vital in decision making and good decisions rely on clean data Random Errorunknown and unpredictable changes, this error can be minimized by larger samples Systematic Errorconstant measruement error Omission errorsomething left out or an action not taken Outliersobservation points (numbers) that are distant from others
