You have a dataset with a large number of missing values. What strategies can you use to depict this in your data visualization?
- Ignore the missing values, because they can't be visualized
- Only include complete cases in the visualization
- Replace all missing values with the mean
- Use a different color or pattern to indicate missing values
Missing values can be indicated in data visualizations using a different color or pattern. This strategy allows viewers to see where data is missing, which can be informative in itself. Ignoring or inaccurately replacing missing values can lead to misleading visualizations.
