CompTIA Data+ DA0-002 (V2) Practice Question

The correct answer is that the 'Store_Region' column contains inconsistent values. This is a common data quality issue where variations like ' North' (with a leading space), 'N. Region', or misspellings prevent the filter from correctly grouping all intended records. When the analyst selects 'North', the slicer only includes rows with that exact value, excluding the variations. The other options are less likely. A slow refresh rate would affect the timeliness of the data, not the logical behavior of a filter on existing data. Excessive load time is a performance issue, not a data accuracy issue related to filtering logic. An incorrect join type would likely cause more widespread issues, such as missing data for all regions or incorrect totals, rather than affecting only a subset of records for a single filter value.
