What is skewness?

Skewness is when numbers lean more to one side than the other, like a seesaw that’s not balanced.

Imagine you have a bag of candies. Most of them are small, but there's one huge candy in there, so big it feels like a rock! When you dump all the candies on a table, they don’t spread out evenly; instead, they bunch up near the small ones, with that huge candy sticking out far to one side. That’s skewness, when most of the things are grouped together, but there's an extreme value pulling everything toward one end.

What Skewness Looks Like

If you draw a picture of how the candies are spread out, it might look like a crooked line, not straight, not symmetrical. If the big candy is on the right side, the line leans to the left; that’s left skew or negative skew.

But if most of your candies are huge and one is tiny, like a single pebble in a bag full of rocks, then the line would lean to the right, that's right skew or positive skew.

Think of it like a class where most kids are average height, but one kid is super tall. The line showing their heights will be pulled up by that one really tall kid, just like skewness pulls numbers toward one side!
