To analyze column distribution of a data source in Power Query Editor, which action should you take?

Enabling the Column Profile view is the correct action to analyze the column distribution of a data source in Power Query Editor. The Column Profile view provides a comprehensive overview of each column within your dataset, detailing aspects such as data type, distinct values, and distribution patterns. It allows users to visualize and assess the quality of the data, making it easier to identify any anomalies, outliers, or trends within the data. This feature essentially displays statistical summaries and histograms for each column, facilitating a deeper understanding of the data's characteristics.

Other options do not directly pertain to analyzing column distribution. Modifying the Advanced settings in Data Source Settings pertains to configuring connections or performance settings rather than analyzing data. Accessing the Query Settings allows for adjustments in query properties but does not provide the specific insights into column distribution that the Column Profile view offers. Changing the Edit Permissions settings is focused on managing access rights rather than on data analysis. Thus, enabling the Column Profile view stands out as the most effective method in Power Query for analyzing the distribution of data in columns.
