What is the default type for a measure if none is specified?

• A. integer
• B. string
• C. float
• D. boolean

Answer: (B)

The default type for a measure in LookML, when none is specified, is actually float. Measures are typically used to perform calculations such as sums, averages, or counts, and floating-point numbers allow for the representation of decimal values which can be crucial for precision in these calculations. Choosing an incorrect default type, like string, would not align with the primary functionality of measures in LookML, as measures are meant for numeric calculations rather than textual data representation. In most data modeling languages, including LookML, the nature of measures inherently implies a numerical format; therefore, specifying the default type as float supports the intended operations on these values. This is important for ensuring that analytical functions can be performed accurately and efficiently within the Looker environment.
