Research question In this case‚ author solved four questions: 1. Is standard costing used in Dubai? 2. How important are various functions in standard costing? 3. How frequently are various techniques and cost standards used in standard costing? 4. How important is the analysis of variance for control purposes? Research design They collected the

THE LOGIC OF ANOVA ANalysis Of VAriance (commonly abbreviated as ANOVA)‚ more specifically‚ we will take up an application known as one-way ANOVA. Many statisticians think of ANOVA as an extension of the difference of means test because it’s based‚ in part‚ on a comparison of sample means. At the same time‚ however‚ the procedure involves a comparison of different estimates of population variance—hence the name analysis of variance. Because ANOVA is appropriate for research involving three or

Wk 4‚ DQ1 How would you explain the analysis of variance‚ assuming that your audience has not had a statistics class before? When one does a study of data‚ generally this implies an evaluation of the "mean" or average of that data. .i.e. What is the average time it takes a 5th grader to complete his final math exam? A t test is used to test differences between two means. i.e. the mean of the experiment group vs a control group. An ANOVA test‚ on the other hand‚ is indicated when there are
