(BQ) Chapter 17: Additional topics in variance analysis. In this chapter, we discuss additional variances to illustrate some of the ways the basic variance analysis model can be extended and adapted to specific circumstances. The basic principles are exactly the same as those we discussed in chapter 16.

We investigate fullscale shortestderivation parsing (SDP), wherein the parser selects an analysis built from the fewest number of training fragments. Shortest derivation parsing exhibits an unusual range of behaviors. At one extreme, in the fully unpruned case, it is neither fast nor accurate. At the other extreme, when pruned with a coarse unlexicalized PCFG, the shortest derivation criterion becomes both fast and surprisingly effective, rivaling more complex weightedfragment approaches.

This chapter explores how budgets can be adjusted so that meaningful comparisons to actual costs can be made. This chapter include objectives: Prepare a flexible budget, prepare a report showing activity variances, prepare a report showing revenue and spending variances, prepare a performance report that combines activity variances and revenue and spending variances, prepare a flexible budget with more than one cost driver, understand common errors made in preparing performance reports based on budgets and actual results.

Lecture Managerial accounting (14/e)  Chapter 10: Standard costs and operating performance measures
This chapter extends our study of management control by explaining how standard costs are used by managers to control costs. It demonstrates how to compute direct materials, direct labor, and variable overhead variances. The chapter also defines some nonfinancial performance measures that are frequently used by companies.

Risk analysis for well known, well documented and steadystate systems (or stable phenomena) can be performed by methods of statistical analysis of available data. These include, for example, maximum likelihood estimations, and analyses of variance and correlations. More generally, these methods require a projection in the future of risk estimates based on a sufficient sample,

(BQ) This paper presents an investigation of the effects of machining variables on the surface roughness of wireEDMed DC53 die steel. In this study, the machining variables investigated were pulsepeak current, pulseon time, pulseoff time, and wire tension. Analysis of variance (ANOVA) technique was used to find out the variables affecting the surface roughness. Assumptions of ANOVA were discussed and carefully examined using analysis of residuals. Quantitative testing methods on residual analysis were used in place of the typical qualitative testing techniques.

15 Budgetary Control. In this chapter, we describe the budgetary control that takes place in organizations through the techniques of ﬂexible budgets and variance analysis. However, we caution against variance analysis in circumstances where this could conﬂict with more broadly based improvement strategies within the business.
