LABOR COST VARIANCE CAN BE SPLIT INTO • Direct labor rate variance (P) Calculation: actual total labor costs - (total actual labor hours worked x budgeted labor hour rate) Interpretation: calculates the portion of labor costs variance driven by the changed labor rate per hour Possible reasons for variances: changes in staff qualification and skills‚ general increase of wages in economy‚ premiums paid to finish a job quickly‚ poor budgeting • Direct labor quantity (efficiency) variance (P) Calculation:

Day Exercise Analysis When looking at the current state of my exercise habits consists of walking at least 2 miles a day and jog 2 miles‚ stretches‚ and 30 minutes of deep cardio. I like to get up in the morning and start off with my stretching so that I do not become sore later on in the day‚ and it helps relax me and get me ready for my day. I like to stretch for at least 15-20 minutes every morning and stretching also helps with waking me up as well. After I get done with my stretches I will

exposed to three different counselling approaches. The dependent variable‚ self-concept‚ may be measured through a standardized self-concept instrument which yields interval scores for the subjects. In this problem‚ application of the one-factor ANOVA will test the following hypothesis: There is no significant difference in self-concept among the three groups of students exposed to different counselling approaches.

Applying ANOVA and Nonparametric test In the simulation‚ I selected the Kruskal-Wallis test which is used when it is difficult to meet all of the assumptions of ANOVA. The Kruskal-Wallis test is a nonparametric alternative to one way ANOVA. This test is used to compare three or more samples‚ to test the null hypothesis that the different samples in the comparison drawn from the same distribution or from distributions with the same median. Interpretation of the Kruskal-Wallis test is basically similar

I chose exercise 14.3 II. In this exercise we had to watch the local news‚ national news‚ and the local paper and answer the following questions‚ how many stories are apparently intended to appeal to our emotions and our sympathies‚ which stories seem to have been intended to grab attention by appealing to our curiosity or love of scandal‚ which seemed to be selected for their entertainment value‚ and how many stories seem intended to make us fearful for our safety or grateful for our security?

Limitations of using variance analysis for performance evaluation Variance analysis is the process of examining in detail each variance between actual and standard costs to determine the reasons why budgeted results were not met. Despite the advantages highlighted above‚ there are several limitations that may result in the use of variance analysis for performance evaluation. I.
