Which of the following is true of a measure in Power Pivot technology? A measure is the same thing as a calculated column. A measure is a summarization of any single column in a Data Model table. A measure is a summarization of data in one or more tables of a Data Model created with a DAX formula to be used in the Values area of a plvot table, A measure is a formula for summarizing data to be used in the Values area of a pivot table, and it can be based on the usual built-in Excel functions; no DAx functions are necessary.

1. A measure is **not** the same thing as a calculated column. - A calculated column computes a value for every row in a table, whereas a measure computes results on the fly based on the context in which it is used. 2. A measure is **not** simply a summarization of a single column in a data model table; - It is a dynamic computation that can summarize data across one or more tables. 3. A measure **is** a summarization of data in one or more tables of a data model created with a DAX formula to be used in the Values area of a pivot table. - This option accurately describes a measure. 4. A measure is **not** a formula for summarizing data that can be based solely on the usual built-in Excel functions without DAX. - Measures are defined using DAX (Data Analysis Expressions) for computations. Thus, the correct statement is: \( \text{A measure is a summarization of data in one or more tables of a Data Model created with a DAX formula to be used in the Values area of a pivot table.} \)
