Final answer:
The equation for labor efficiency variance (quantity) is Labor Efficiency Variance (quantity) = Standard Labor Hours - Actual Labor Hours.
Step-by-step explanation:
The equation for labor efficiency variance (quantity) can be calculated using the following formula:
Labor Efficiency Variance (quantity) = Standard Labor Hours - Actual Labor Hours
To calculate the labor efficiency variance (quantity), you need to know the standard labor hours and the actual labor hours. The standard labor hours refer to the amount of time it should take to complete the required quantity of output, while the actual labor hours represent the actual time taken. The variance is obtained by subtracting the actual labor hours from the standard labor hours.
