What does uniform weight range refer to in terms of variation?

Uniform weight range in the context of variation refers to a specified percentage that indicates the allowable deviation from a standard or expected weight. In this case, a uniform weight range of 20% means that whatever the standard weight is, a variation of up to 20% above or below that weight is acceptable. This percentage allows for flexibility and accommodates the natural variations that can occur in weight measurement, particularly in settings where products may not have a strictly consistent weight.

The other options provided offer specific pound values or percentage that might not convey the necessary standardization or flexibility required in weight verification practices. By using a percentage like 20%, it scales proportionally with the item’s weight, ensuring that the acceptable range adjusts appropriately based on the actual weight of the object in question. This method is crucial in many measurement and regulatory contexts, as it maintains consistency and reliability in weight-related decisions.
