Unequal in Variance
Equal in Variance
This is not a legitimate question. However, based on assumptions I guess the answer that you are looking for is heterogeneous mixtures.
Favourable variance is that variance which is good for business while unfavourable variance is bad for business
The other assumptions are listed in the related link. The answer you are looking for is the same variance or standard deviation.
Negative price variance is when the cost is less than budgeted. Volume variance is a variance in the volume produce.
efficiency variance, spending variance, production volume variance, variable and fixed components
There are 7 variances associated with a budget ( which are generally calculated for controlling purposes) 1- Material Price variance 2- Material Quantity variance 3- Labor rate variance 4- Labor efficiency variance 5- Spending variance 6- Efficiency variance 7- Capacity variance
Variance
heterogeneous
It is a heterogeneous mixture. The meat balls and the noodles are not mixed together and distributed evenly. Chocolate milk would be Homogeneous because the chocolate powder and the milk have mixed evenly.
heterogeneous mixture
Since Variance is the average of the squared distanced from the mean, Variance must be a non negative number.
