That is, S ‾ = S 1 + ⋯ + S k k. Because the expected value of S ‾ is not equal to σ, we divide it by a constant c ( n) that depends on the subgroup sample size n, to obtain an estimator whose mean is σ. That is, we use the estimator S ‾ / c ( n), which is such that. E [ S ‾ / c ( n)] = σ.

In group theory, a branch of mathematics, given a group G under a binary operation ∗, a subset H of G is called a subgroup of G if H also forms a group under the operation ∗. More precisely, H is a subgroup of G if the restriction of ∗ to H × H is a group operation on H. This is often denoted H ≤ G, read as "H is … See moreSince the normal subgroup is a subgroup of H, its index in G must be n times its index inside H. Its index in G must also correspond to a subgroup of the symmetric group S n, the group of permutations of n objects.
