techniques can be used to analyze nominal level data to describe variables‚ examine relationships among variables‚ and determine differences between groups in distribution-free or non-normally distributed samples. The assumptions of nonparametric statistics are: (1) values from measurement of study variables need not be normally distributed in the sample‚ and (2) the level of measurement of study variables is usually nominal or ordinal. The mode is the only measure of central tendency that can be calculated

QUESTION 1 The managing partner for Westwood One Investment Managers Inc. gave a public seminar in which she discussed a number of issues‚ including investment risk analysis. In that seminar‚ she reminded people that the coefficient of variation can often be used as a measure of risk of an investment. To demonstrate her point of view‚ she used two hypothetical stocks as examples. She let x equal the change in assets for a $1‚000.00 investment in stock1 and y reflect the change in assets for a
