? You have recently retired and made your new home near the campus of a prestigious college. One afternoon as you walk through the lovely campus, you notice that a public lecture will take place on the subject of great interest to you.... Business Analytics: New Science or Passing Fad. The lecturer is renown Professor of Data Science, Yu Chi Liu. You decide to attend and sit near the front of a packed lecture hall (your hearing loss makes it necessary). Prof. Liu states that business analytics begins with the following: "collection, organization, and manipulation of data." You sheepishly raise your hand and Prof. Liu calls on you. You ask: "What is data manipulation Prof. Liu?" She smiles and says: "You tell me." She offers you the choices below. Which is the best choice? The act of recording data, either by collecting responses to questions or some other form of data entry The systematic transcription of data into a data management system or platform that will permit analysis le.g. an Excel workbook or Microsoft SQL Server) The act of examining a data set for missing data elements or elements that are impossible or improbable (e.g., a value that is a text value when it should be a numerical value) The act of changing data into a form that is more convenient or compatible for analysis, for example, taking a numeric value (say $104,091.43) and replacing it with a categorical designation (say between $90,000 and $125,000)
