For example, consolidating "USA," "U.S.A," "United States," and "US" into one uniform label, like "United States," ensures that all data entries are interpreted consistently. This process is essential in data cleaning, as inconsistencies in categorical data can lead to inaccurate analysis, skewed results, and duplications in reporting. A uniform categorical format enables reliable grouping, sorting, and filtering for analysis. The other options are incorrect because: • Option 1 (Filtering duplicates) removes identical rows but doesn’t address inconsistency in a single field. • Option 2 (Using normalization) only applies to numeric scaling, not categorical consistency. • Option 3 (Applying data transformation) would encode inconsistencies rather than correct them. • Option 5 (Converting to uppercase) helps with case sensitivity but does not fully standardize variations.
