  2. Variable cost - Wikipedia

    en.wikipedia.org/wiki/Variable_cost

    Variable costs are sometimes called unit-level costs as they vary with the number of units produced. Direct labor and overhead are often called conversion cost, [3] while direct material and direct labor are often referred to as prime cost. [3] In marketing, it is necessary to know how costs divide between variable and fixed. This distinction ...

    Purdue University prohibits students soliciting answers using Chegg's homework help: "While Chegg can be helpful to access textbooks and more practice problems, using this resource to find assignment answers is considered academic dishonesty because it is a form of copying and plagiarism.".

  4. Standard cost accounting - Wikipedia

    en.wikipedia.org/wiki/Standard_cost_accounting

    An important part of standard cost accounting is a variance analysis, which breaks down the variation between actual cost and standard costs into various components (volume variation, material cost variation, labor cost variation, etc.) so managers can understand why costs were different from what was planned and take appropriate action to ...

  5. Variance (accounting) - Wikipedia

    en.wikipedia.org/wiki/Variance_(accounting)

    Variance analysis can be carried out for both costs and revenues. Variance analysis is usually associated with explaining the difference (or variance) between actual costs and the standard costs allowed for the good output. For example, the difference in materials costs can be divided into a materials price variance and a materials usage variance.

  6. Price variance - Wikipedia

    en.wikipedia.org/wiki/Price_Variance

    Price variance (Vmp) is a term used in cost accounting which denotes the difference between the expected cost of an item (standard cost) and the actual cost at the time of purchase. [1] The price of an item is often affected by the quantity of items ordered, and this is taken into consideration.

  7. Pre-determined overhead rate - Wikipedia

    en.wikipedia.org/wiki/Pre-determined_overhead_rate

    To avoid such fluctuations, actual overhead rates could be computed on an annual or less-frequent basis. However, if the overhead rate is computed annually based on the actual costs and activity for the year, the manufacturing overhead assigned to any particular job would not be known until the end of the year. For example, the cost of Job 2B47 ...

  9. Bootstrapping (statistics) - Wikipedia

    en.wikipedia.org/wiki/Bootstrapping_(statistics)

    This results in an approximately-unbiased estimator for the variance of the sample mean. [48] This means that samples taken from the bootstrap distribution will have a variance which is, on average, equal to the variance of the total population. Histograms of the bootstrap distribution and the smooth bootstrap distribution appear below.
