What each term means

Harmonic Mean (H): A kind of average suited to sets of rates, such as speeds. It is the number of observations divided by the sum of the reciprocals of each observation.
Total Number of Observations (n): The total count of values or observations in the data.
Sum of the Reciprocals (Σ 1/xᵢ): The sum of the inverse of each value (xᵢ) in the data. The reciprocal of a number is 1 divided by that number.
