  • What is a median? How would you go about calculating a median from a dataset too large to store in memory?
  • What does median represent in statistics, and what strategy would you employ to determine the median of an extremely large dataset?
  • How do you define a median and what approach would you take to calculate it for a dataset that's too large for memory?
  • Can you describe the concept of a median and how to calculate it from a very large dataset not fitting in memory?
  • What is the principle of median in data analysis, and how would you go about finding the median of a large-scale dataset?
  • How would you explain a median and what techniques would you use to compute it from an oversized dataset?
  • What constitutes a median in a dataset, and how can it be calculated if the dataset is too large to be held in memory?
  • Can you delineate what a median is and how you might compute it when dealing with massive datasets?
  • How is a median defined and what method would you utilize to ascertain the median of a dataset that cannot be entirely loaded into memory?
  • Could you explain the median and how you would compute it from a dataset that exceeds memory capacity?
