**Reading 8 – Statistical Concepts and Market Returns**

– LOS 8a: distinguish between descriptive statistics and inferential statistics, between a population and a sample, and among the types of measurement scales

– LOS 8b: define a parameter, a sample statistic, and a frequency distribution

– LOS 8c: calculate and interpret relative frequencies and cumulative relative frequencies, given a frequency distribution

– LOS 8d: describe the properties of a data set presented as a histogram or a frequency polygon

– LOS 8e: calculate and interpret measures of central tendency, including the population mean, sample mean, arithmetic mean, weighted average or mean, geometric mean, harmonic mean, median, and mode

– LOS 8f: calculate and interpret quartiles, quintiles, deciles, and percentiles

– LOS 8g: calculate and interpret 1) a range and a mean absolute deviation and 2) the variance and standard deviation of a population and of a sample

– LOS 8h: calculate and interpret the proportion of observations falling within a specified number of standard deviations of the mean using Chebyshev’s inequality

– LOS 8i: calculate and interpret the coefficient of variation and the Sharpe ratio

– LOS 8j: explain skewness and the meaning of a positively or negatively skewed return distribution

– LOS 8k: describe the relative locations of the mean, median, and mode for a unimodal, nonsymmetrical distribution

– LOS 8l: explain measures of sample skewness and kurtosis

– LOS 8m: compare the use of arithmetic and geometric means when analyzing investment returns
