4.5 Kruskal-Wallis Test Based on the normality test that was done‚ it was shown that the data were not normally distributed so a non-parametric test has to be done instead of a parametric test. Kruskal-Wallis’ test (also called the one-way ANOVA on ranks)‚ was done to determine if there were statistically significant differences between three groups of an independent variable on a continuous variable. 4.5.1 Compare mean AA among the three races in both age groups The Kruskal-Wallis test was done

Chapter 15 The Flexible Budget: Further Analysis of Productivity and Sales Teaching Notes for Cases Case 15-1 Dallas Consulting Group* This case serves as a review of sales variances. Since all costs are fixed‚ it is unnecessary to do a variance analysis based on contribution. Instead‚ the analysis is better done based solely on revenues. The variances shown in Exhibit 1 are computed for the “levels” explained in the “Note on Managing Against Expectations.” Students should recognize

INTRODUCTION TO ONE-WAY ANALYSIS OF VARIANCE Dale Berger‚ Claremont Graduate University http://wise.cgu.edu The purpose of this paper is to explain the logic and vocabulary of one-way analysis of variance (ANOVA). The null hypothesis tested by one-way ANOVA is that two or more population means are equal. The question is whether (H0) the population means may equal for all groups and that the observed differences in sample means are due to random sampling variation‚ or (Ha) the observed differences

Unit 2: Business Resources Amy Doherty D3: Benefits & Drawbacks of Variances Variances can be defined as “A measurement of the spread between numbers in a data set. The variance measures how far each number in the set is from the mean.”1 A variance can be adverse or favourable. An adverse variance is when the actual financial figures for a business are worse than forecasted and a favourable variance is when the actual figures are better than budgeted. A budget is an documented summary

Francisco and Montreal. Furthermore‚ if the tests conclude that there is a difference in mean prices‚ our group will indicate where the prices are higher or lower. Hypothesis Testing For this data set‚ our group has chosen to conduct a one way Analysis of Variance F test (one-way ANOVA F-test). A one-way ANOVA F-test is appropriate in this example since it is a hypothesis technique that is used to compare means from three or more populations. Since the data set reflects the mean prices of residential

Issues: 1. The current variance analysis used for the 1973 fiscal years shows an overall favorable net variance of $71‚700. This is an aggregate net figure based upon the favorable variance due to sales and the unfavorable variance due to operations. This net variance figure fails to highlight areas of deficiency to help identify corrective actions. Furthermore‚ this variance does not indicate the real cause of the favorable overall variance. The success and purpose of variance analysis is reliant on how
