TAILIEUCHUNG - Lecture Statistical techniques in business and economics - Chapter 16: Analysis of ranked data

When you have completed this chapter, you will be able to: Conduct the sign test for single and dependent samples using the binomial and standard normal distributions as the test statistics, conduct a test of hypothesis for dependent samples using the Wilcoxon signed-rank test, conduct and interpret the Wilcoxon rank-sum test for independent samples,. | Chapter 16 Analysis of Ranked Data 1. Conduct the sign test for single and dependent samples using the binomial and standard normal distributions as the test statistics 2. Conduct a test of hypothesis for dependent samples using the Wilcoxon signed-rank test Chapter Goals When you have completed this chapter, you will be able to: and. 3. Conduct and interpret the Wilcoxon rank-sum test for independent samples Chapter Goals 4. 5. 6. Conduct and interpret the Kruskal-Wallis test for several independent samples Compute and interpret Spearman’s coefficient of rank correlation Conduct a test of hypothesis to determine whether the correlation among the ranks in the population is different from zero Terminology Range is the difference between the largest and the smallest value Only two values are used in its calculation It is influenced by an extreme value It is easy to compute and understand The Sign Test The Sign Test is based on the sign of a difference between two related observations
