When missing data points are randomly distributed, imputing values using the mean (for continuous data) or median (for skewed distributions) can be an effective technique. This approach maintains the dataset’s overall structure and helps reduce potential bias introduced by missing values. By substituting missing values with central tendencies, analysts can preserve statistical relationships without significantly distorting the data, ensuring a more accurate analysis. Option A is incorrect as removing rows may lead to a significant data loss, especially if many rows contain missing values. Option C is incorrect because dropping columns with missing values reduces feature dimensions, potentially discarding useful information. Option D is incorrect as placeholder values can introduce bias or mislead analysis, especially if the placeholder value skews the distribution. Option E is incorrect because ignoring missing values leaves gaps, making it difficult to perform accurate analysis.
