When data analysts activate their data analysis capabilities, they are said to turn on their _____.

In the context of data analysis, when analysts "turn on" their capabilities, they engage their ability to view and interpret data through a particular perspective, often referred to as a "data lens." This term encapsulates the tools and methodologies that allow analysts to filter, visualize, and derive insights from data, helping them to better understand trends, patterns, and anomalies. By activating their data lens, analysts can focus on specific aspects of the data and make informed decisions based on their analysis.

The other options, while related to data analysis, do not capture the essence of the transformative engagement that a data lens represents. An insight engine typically refers to the automated systems that generate insights but doesn't describe the analyst's active role in interpreting data. An analysis framework may provide structure to the analytical process but does not directly signify the act of activating analysis capabilities. A reporting platform is primarily focused on the dissemination of findings, rather than the analytical manipulation and exploration of data itself. Thus, "data lens" is the most fitting term in this scenario.
