A right-skewed distribution has a long right tail. Right-skewed distributions are also called positive-skew distributions. That's because there is a...

My Note:

If a distribution is symmetrical, each side of the distribution is a mirror image of the other. For a symmetrical, bell-shaped distribution (known as the normal distribution), the mean, median, and mode of the distribution are equal. The normal distribution can be completely described by its mean and variance.

A distribution is skewed if one of its tails is longer than the other...

What is long tail? - Definition from WhatIs.com

The long tail is a frequency distribution pattern in which occurences are most densely clustered close to the Y-axis and the distribution curve tapers along the X-axis. The long tail refers to the low-frequency population displayed in the right-hand portion of the graph, represented by a gradually sloping distribution curve that becomes asymptotic to the x-axis. In most applications, the number of events in the tail is greater than the number of events in the high frequency area,...

Overview - Long-tailed Jaeger (Stercorarius longicaudus ...

Acknowledgments

This is the smallest of the three jaegers. It is also the one which has the longest of all central tail feathers. As in the Parasitic (Stercorarius parasiticus) the tail streamers are pointed, but in the Long-tailed they are long and flow and move with the air, unlike the shorter, stiffer streamers of the Parasitic. Furthermore as an adult this jaeger only exists as a pale morph, although juvenile and immature stages are more variable in coloration. It is an Arctic breeder and pelagic during the non breeding season. In the Arctic it takes dry and often rocky tundra, such that it is the only jaeger that is found breeding...
