What type of value should be selected for a custom calculation row?

Selecting a numeric formula for a custom calculation row is essential because calculations typically require numeric input to derive meaningful results. A numeric formula allows for operations such as addition, subtraction, multiplication, or division, which are fundamental to obtaining quantified data insights.

In scenarios where you need to derive totals, averages, or any other form of quantitative analysis, using a numeric formula ensures that the values you are working with can be manipulated mathematically. This is crucial in healthcare settings, as accurate data calculations can influence clinical decisions, reporting, and overall management of patient care.

Other options, such as text formulas, would not be suitable for calculations since they are designed for string manipulation and do not support mathematical operations. Boolean values represent truth values (true/false) and are also not applicable for performing numerical calculations. Data arrays are collections of data but do not directly provide a format for calculations as a numeric formula does. Thus, choosing a numeric formula effectively aligns with the necessary functionality required for custom calculations.
