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 ...
This algorithm can easily be adapted to compute the variance of a finite population: simply divide by n instead of n − 1 on the last line.. Because SumSq and (Sum×Sum)/n can be very similar numbers, cancellation can lead to the precision of the result to be much less than the inherent precision of the floating-point arithmetic used to perform the computation.
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.
In 2011, Chegg acquired Zinch, a scholarship search and networking service for high school students and college recruiters, and continues to offer the service, under the Chegg brand name. [30] Chegg acquired software company 3D3R in late 2011 to develop its digital textbook product, kickstart its mobile product group, and open an engineering ...
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 ...
In statistics, one-way analysis of variance (or one-way ANOVA) is a technique to compare whether two or more samples' means are significantly different (using the F distribution). This analysis of variance technique requires a numeric response variable "Y" and a single explanatory variable "X", hence "one-way".
Chegg's 2024 first quarter revenue of $174.4 million was down 7% compared to the same period a year prior and down nearly 14% from the first quarter of 2022.
