How to solve for arithmetic mean
WebAug 17, 2024 · Find its arithmetic mean. Solution: As we know, A.M = Sum of all numbers/Total no. of items. A.M = (10 + 12 + 22 + 28)/4 = 72/4 = 51. Therefore, the mean is 51. Question 2: If the arithmetic means of 5 observations 6, 7, 5, x, 10 is 6. Find the value of x. Solution: Given, The 5 observations are 6, 7, 5, x, 10. no. of items (n) = 5. Arithmetic ... WebHowever, you could use something like: def mean (numbers): return float (sum (numbers)) / max (len (numbers), 1) >>> mean ( [1,2,3,4]) 2.5 >>> mean ( []) 0.0. In numpy, there's numpy.mean (). A common thing is to consider that the average of [] is 0, which can be done by float (sum (l))/max (len (l),1).
