Fluctuation is probably the closest (depending on context).
These also have similar meanings:

variation, variance, modification, diversity, difference, change
The coefficient of simple determination tells the proportion of variance in one variable that can be accounted for (or explained) by variance in another variable. The coefficient of multiple determination is the Proportion of variance X and Y share with Z; or proportion of variance in Z that can be explained by X & Y.
efficiency variance, spending variance, production volume variance, variable and fixed components
Variance
Yes. If the variance is less than 1, the standard deviation will be greater that the variance. For example, if the variance is 0.5, the standard deviation is sqrt(0.5) or 0.707.
variation, variance, modification, diversity, difference, change
Alteration, modification, transformation, conversion, substitution, replacement, trade, exchange, adaption, variance...
difference; change, or amount of change
It is a report to see how a business is doing by comparing one set of figures to another. The variance is the number in between and can be useful in forecasting or to chart performance.
Variance
Favourable variance is that variance which is good for business while unfavourable variance is bad for business
The coefficient of simple determination tells the proportion of variance in one variable that can be accounted for (or explained) by variance in another variable. The coefficient of multiple determination is the Proportion of variance X and Y share with Z; or proportion of variance in Z that can be explained by X & Y.
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
