Imagine you have a dataset where only 5% of the rows contain missing values. What potential problems could arise if you choose to use listwise deletion?
- It could cause all of the above problems
- It may distort the original data distribution
- It may lead to a significant reduction in sample size
- It might introduce selection bias
Even though only 5% of the rows contain missing values, using listwise deletion could still lead to a significant reduction in sample size, potential distortion in the original data distribution, and introduce selection bias. These problems may affect the statistical power and the representativeness of the analysis.
