Data Science Interview Questions: Day 2

Navigating interviews can be daunting, but you can significantly ease the journey with thorough preparation. Here are the five data science interview questions.

1. What is statistical sampling, and why is it important in data analysis?

Statistical sampling is selecting a subset of individuals, observations, or data points from a larger population to conclude the entire population. This technique is crucial in data analysis because it allows analysts to make inferences about a population’s characteristics without needing to examine every single data point, which can be impractical or impossible in many cases. By using proper sampling methods, data analysts can obtain accurate, representative insights while saving time and resources, reducing costs, and improving the efficiency of the data collection process.
