What is material cost variance?
The material cost variance denoting the difference between the standard cost of materials and actual cost of matrials. The material cost variance is between the standard material cost for actual production in units and actual cost. The total cost is usually determined by two differenct factors of influence viz quantity of materials utilized/ required and price of the materials. The fluctuations in the material cost are only due to the fluctuations in the utility of materials due to many factors. Material cost variance can be computed into two different ways: DIRECT METHOD AND INDIRECT METHOD material cost variance= Standard cost of materials for actual output- actual cost of raw materials. MCV=(S Q AO X SP)-(AQ X AP) Indirect Method: material cost variance= Material price variance (MPV)+Material usage Variance
It is best to isolate the material quantity variance when the materials are purchased?
false- it is best to isolate them once you know how much of the material has been used. If you don't know how much is used, you can't get a variance to evaluate efficiency of how materials were used.
Standard deviation considered a crude measure of variance?
No. Well not exactly. The square of the standard deviation of a sample, when squared (s2) is an unbiased estimate of the variance of the population. I would not call it crude, but just an estimate. An estimate is an approximate value of the parameter of the population you would like to know (estimand) which in this case is the variance.
How do you calculate a budget variance as a percentage?
actual budget/budget = variance%
Set of 25 numbers has standard deviation 6 then it's variance is?
Square the standard deviation to obtain the variance. The variance is 62 or 36.
