BUS 300 Lecture Notes - Lecture 10: Standard Deviation, Diminishing Returns, Frequency Distribution
Document Summary
Determination of sample size a review of statistical theory. Make inferences about whole populations from a sample. Variables in a sample or measure computed from sample data. Variables in a population or measured characteristics of the population. A set of data organized by summarizing the number of times a particular value of a variable occurs. A frequency distribution organized into a table (or graph) that summarizes percentage values associated with particular values of a variable. The long-run relative frequency with which an event will occur. Average pay could mean there"s a highly paid executive and many low-paid employees. The percentage of elements that meet some criterion. Median: the midpoint; the value below which half the values in a distribution fall. Mode: the value that occurs most often. The distance between the smallest and the largest values of a frequency distribution. Variance: a measure of variability of dispersion, its square root is the standard deviation.
