And we assume independent errors. 267 268 CHAPTER 11. TWO-WAY ANOVA Two-way (or multi-way) ANOVA is an appropriate analysis method for a study with a quantitative outcome and two (or more) categorical explanatory variables. The usual assumptions of Normality‚ equal variance‚ and independent errors apply. The structural

Analysis of Variance Lecture 11 April 26th‚ 2011 A. Introduction When you have more than two groups‚ a t-test (or the nonparametric equivalent) is no longer applicable. Instead‚ we use a technique called analysis of variance. This chapter covers analysis of variance designs with one or more independent variables‚ as well as more advanced topics such as interpreting significant interactions‚ and unbalanced designs. B. One-Way Analysis of Variance The method used today for comparisons of

Cost Variance Analysis Presented by : Edmund C. Cabrera MBA Student Universidad de Manila Definitions STANDARD COSTS – are predetermined or target unit costs of production which should be attained under efficient conditions. It is the amount and costs of direct material‚ direct labor‚ and factory overhead required to produce one unit of finished product. STANDARD COST SYSTEM – is an accounting system which uses standard costs rather than actual costs to account for units as they flow through

organisation uses budgets to control the costs for a limit of period by equating what was spent during that time to the master budget. This benefits B.A as they would be observing all their expenses and returns which prevent them from surpassing their budgets. This business uses budgets because it is a valuable tool when evaluating B.A performance and value of their budget. Budgeting is beneficial to B.A as it helps them with planning orientation such as it helps to create a budget plan where it can
