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.
