# Thread: Determining the Direction of Skew?

1. ## Determining the Direction of Skew?

Ideally speaking, a graph like this is described to have a skew to the right:

and a graph like this is described to be symmetrical:

but in most cases, the graphs aren't clear.

What would the skew of this graph be?
I think it might be "skewed to the left", but the bars on the right confuse me (since most of them have the same value).
Also, this would be bimodal?

Note: I made the graphs myself.

2. I agree that the graph looks left-skewed and unimodal.

I was always taught that if the mean is to the left of the median, the graph is left skewed and if the mean is to the right of the graph, the graph is right-skewed. It's a good way to determine skewness but isn't fool proof.

Why not just calculate the skew? It is just the satandardised third central moment.
