SENIOR-DATA-SCIENTIST sample questions

2 questions from the SENIOR-DATA-SCIENTIST practice set, with the answer and explanation.

  1. Question 1
    A senior data scientist must summarize session length for a product where a few power users have very long sessions. Which summary gives the most robust picture of a typical user?
    • A.
      The median, reported together with the interquartile range.
    • B.
      The arithmetic mean only, computed across all sessions including the power users.
    • C.
      The maximum observed session length.
    • D.
      The total of all session lengths.
    Show answer

    Correct answer:

    • A.
      The median, reported together with the interquartile range.

    Explanation

    The median and interquartile range describe the middle of the distribution and are not dragged upward by the power users. The arithmetic mean is the most tempting choice, but it reflects the long tail rather than a typical user. The maximum and the total describe extremes or volume, not a typical session.
  2. Question 2
    Bootstrapping estimates a sampling distribution by resampling the observed data with replacement.
    • A.
      True
    • B.
      False
    Show answer

    Correct answer:

    • A.
      True

    Explanation

    The bootstrap draws many resamples of the same size from the observed data with replacement and uses the spread of the resulting statistics to approximate uncertainty. It needs no closed-form distribution. The statement is true.
