What DAX function can be used to calculate the average overall satisfaction score based on survey responses?

The function that is most appropriate for calculating the average overall satisfaction score based on survey responses is AVERAGE. This function directly computes the arithmetic mean of a set of values, making it simple and effective for scenarios where you want to find an overall average from a column of numbers, such as scores from survey responses.

Using AVERAGE would involve applying it to the relevant column containing the satisfaction scores, allowing for a straightforward way to derive the average without needing additional filters or calculations. It efficiently takes into account all numerical entries in the specified range, providing a clear and concise outcome that reflects the overall satisfaction level as reported in the survey.

Other functions like AVERAGEX are more suited for calculations involving rows in a table or when more complex expressions are necessary. AVERAGEIF, on the other hand, has conditional functionality that might not be required if the intention is to simply determine an average without any conditions. Meanwhile, CALCULATE is generally used to modify filter context or apply filters which may not be necessary in this straightforward average calculation.
