WebApr 23, 2024 · Suppose that the distribution of X is symmetric about a. Then E ( X) = a skew ( X) = 0. Proof The converse is not true—a non-symmetric distribution can have skewness 0. Examples are given in Exercises (30) and (31) below. skew ( X) can be expressed in terms of the first three moments of X. WebFor p = 0.5 and large and small n, the binomial distribution is what we call symmetric. That is, the distribution is without skewness. For example, here's a picture of the binomial distribution when n = 15 and p = 0.5: 0 1 2 3 4 5 … WebMay 12, 2024 · Saying a random variable X has a symmetric distribution means that X and − X have the same distribution. This means that for any function f, if E [ f ( X)] exists then so does E [ f ( − X)] and they are equal. So take f ( x) = x n with n odd. If X has an n th moment, then E [ X n] exists and so. do i rinse after using mouthwash
