An alternative proof of Theorem 2 may be based on

the fact that if X1, X2, ..., and Xn are independent ran-
dom variables having the same Bernoulli distribution

with the parameter θ, then Y = X1 + X2 +···+ Xn is
a random variable having the binomial distribution with
the parameters n and θ.
Verify directly (that is, without making use of the fact
that the Bernoulli distribution is a special case of the
binomial distribution) that the mean and the variance of
the Bernoulli distribution are μ = θ and σ2 = θ (1 − θ

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
