..function::harmonic_mean(data, weights=None) Return the harmonic mean of *data*, a sequence or iterable of real-valued numbers. real-valued numbers. If *weights* is omitted or *None*, then equal weighting is assumed. The harmonic mean, sometimes called the subcontrary mean, is the ...
In MS Excel, what does it mean when a cell is populated with hashtags? Use Python for the following. You know that the Taylor Series for sin x is sum_k=0 ^infty (-1)^k x^2k+1 (2k+1)! . We can truncate the series to get an approximation for sin x as follows: sin x = ...
For two terms 'a' and 'b': Harmonic Mean = (2 a b) / (a + b) For two numbers, if A, G, and H are respectively the arithmetic, geometric and harmonic means, then A≥ G ≥ H A H = G2, i.e., A, G, H are in GP ...
Theaverageis the common term for the mean. They can be used interchangeably. The mean is different from the median and the mode in that it is a measure of the central tendency that is calculated from the data. As such, there are different ways to calculate the mean based on the type ...
