A data analyst is working for a shipping company and calculating the volume of boxes according to the following formula: volume = height ?width ?depth. Which of the following variable types…

A derived variable is one whose value is computed through a mathematical operation or transformation applied to one or more other variables. In this scenario, 'volume' is explicitly calculated using 'height', 'width', and 'depth', making it a prime example of a derived variable.

Normalized variables typically refer to data scaled to a standard range or reduced in redundancy, which does not apply to a direct calculation like volume.

Concatenated variables are formed by joining textual data, not by performing arithmetic operations on numerical values.

Aggregated variables involve summarizing data from multiple entries or observations, whereas 'volume' is calculated for a single distinct entity from its own properties.
