QuestionQ21

Data science concepts

A remote weather sensor malfunctions, producing temperature readings above the normal range, which was approximately 69.8°F (21°C).

Ignoring units, what is the correct magnitude order of these key measures?

  • A Mean> Median > Skewness > 0(A right skew and a mean greater than the median)
  • B Median > Mean > Skewness > 0(A right skew and a median greater than the mean)
  • C Mean > Median > 0 > Skewness(A left skew and a mean greater than the median)
  • D Median > Mean > 0 > Skewness(A left skew and a median greater than the mean)
Explanation

Unusually high readings form a right-tailed (positively skewed) distribution. High-end outliers pull the mean above the median, and right skewness is greater than zero.
