Getting Started Ch1 Notes Material Extracted From Textbook (Brase, Charles Henry., and Corrinne Pellillo. Brase. Understandable Statistics: Concepts and Methods​ . 11th ed. N.p.: Cengage Learning, n.d. Print.) 1.1 Statistics: The study of how to collect, organize, analyze, and interpret numerical information from data. It is both the science of uncertainty and the technology of extracting information from data. ● Statistics helps people make decisions ● Statistics is a way to examine information ● Make inferences about populations by looking at samples ● The accuracy of a properly applied statistical procedure depends on the accuracy of the data (4). Data Individuals:​ are the people or objects included in the study. Variable:​ a characteristic of the individual to be measured or observed. Quantitative Variable: ​ has a value or numerical measurement for which operations such as addition or averaging makes sense. Qualitative Variable:​ (Also called categorical variations) describes an individual by placing the individual into a category or group, such as male or female. “For instance, if we want to do a study about the people who had climbed Mt. Everest, then the individuals in the study are all people who have actually made it to the summit. One variable might be the height of the individuals (5). Other Variable Examples: Quantitative ­ weight, age, income Qualitative ­ gender, nationality Sources of Data Population Data:​
