This question evaluates your critical thinking and problem-solving abilities.

If that’s not possible, I use statistical methods to estimate missing values and clearly communicate the limitations of my analysis to stakeholders, ensuring they understand the potential impact on decision-making.”

A/B Testing and Experimentation
