TAILIEUCHUNG - Lecture Quantitative investment analysis: Chapter 3 – CFA Institute

Chapter 3 – Statistical concepts and market returns. This chapter include objectives: Differentiate between a population and a sample, explain the concepts of a parameter and a sample statistic; explain the differences among the types of measurement scales; define, calculate, and interpret a holding period return (total return); | Statistical concepts and market returns 1 Populations and samples The subset of data used in statistical inference is known as a sample and the larger body of data is known as the population. The population is defined as all members of the group in which we are interested. 2 Sample Population LOS: Differentiate between a population and a sample. Page 62 Even if we could observe all the members of a population, it is often costly to do so in terms of time, money, and/or computing power. The additional benefit gained is not typically worth the additional cost. The field of statistics is specifically designed to alleviate the need to observe an entire population. In order for a sample drawn from a population to be useful in statistical inference, it needs to have been created with some specific attention to its properties as detailed in Chapter 6. We refer to a sample with this desirable property as being “characteristic” of the population. 2 Parameters and Sample Statistics A population
