<p>Techniques for handling missing values include imputation, where missing values are estimated or replaced based on existing data patterns or statistical algorithms. Another approach is to exclude incomplete data records or variables if they are deemed to have minimal impact on the analysis.</p> Signup and view all the answers

<p>Outliers and inconsistencies can distort analysis and compromise data accuracy. Techniques for handling outliers include winsorizing (replacing extreme values with less extreme values), trimming (removing extreme values altogether), or transforming the data. Inconsistencies can be resolved by standardizing data formats, resolving conflicting entries, or following data validation rules.</p> Signup and view all the answers
