Define the arithmetic mean (AM) of positive numbers x1, …, xn.
Define the arithmetic mean (AM) of positive numbers x1, …, xn.
ক)
AM = (x1 + … + xn)/(n − 1)খ)
AM = (x1 + … + xn)/nগ)
AM = n/(x1 + … + xn)ঘ)
AM = sqrt((x1^2 + … + xn^2)/n)Explanation
The Arithmetic Mean (AM) is fundamentally defined as the sum of all values divided by the count of those values. Therefore, for positive numbers (), the formula is simply the total sum divided by . Option A incorrectly uses in the denominator, which is related to the sample standard deviation's calculation, not the mean. Option C is the reciprocal of the AM. Option D represents the Root Mean Square (RMS), not the Arithmetic Mean.Related questions
