In regression analysis , heteroscedasticity means a situation in which the variance of the dependent variable varies across the data. Heteroscedasticity complicates analysis because many methods in regression analysis are based on an assumption of equal variance.
Variance" is a mesaure of the dispersion of the probability distribution of a random variable. Consider two random variables with the same mean (same aver-age value). If one of them has a distribution with greater variance, then, roughly speaking, the probability that the variable will take on a value far from the mean is greater.
The standard deviation has the same measurement units as the variable and is, therefore, more easily comprehended.
Fixed manufacturing overhead budget variance is?
There is a variance.
Variable overhead cost variance is that variance which is in variable overheads costs between the standard cost and the actual variable cost WHILE fixed overheads cost variance is variance between standard fixed overhead cost and actual fixed overhead cost.
If the estimated materials, labor or overhead costs allocated for a manufacturing order is different from the actual cost of the MO then the potential result is a Manufacturing Overhead Variance.
Combined overhead variance = fixed overhead variance + variable overhead varianceFixed Overhead :which remains fixed and donot change upto certain level of productionVariable Overhead: which keep changing with the change in production units.
Manufacturing cost is variable cost.
Compute the actual and budgeted manufacturing overhead rate
Act. Hr x (Std. Rate - Act. Rate) actual hours times standart rate minus actual rate
volume variance relates to Fixed cost absorption, where as controllable variances arise due difference in actual variable spending per activity measure.
Variable manufacturing overhead cost per direct labor hour means the variable overhead cost spent for one single labor hour and formula is as follows:Variable overhead cost per labor hour = total variable overhead cost / Total direct labor hours
Following is the formula for total costtotal cost = fixed overheads + variable overheads + direct labor + direct material
Total Manufacturing Cost
