WebAug 4, 2024 · A distribution can appear to be left-skewed or negatively skewed graphically and right- or positively skewed numerically, and vice versa. Numerical measures don't necessarily agree even as to sign and in broad terms may only agree exceptionally, notably that all measures of skewness yield zero for an exactly symmetric distribution. A right-skewed distribution is longer on the right side of its peak than on its left. Right skew is also referred to as positive skew. You can think of skewness in terms of tails.
