Symmetry - dot plot graphs.. (1 Viewer)

[Rudroll]

You know the symmetry thing where it says both sides of the graph are exactly the same?

Well in my textbook there are some examples that are nearly symmetrical, but not. They skew towards one side by a small amount and since symmetrical is exactly the same on both sides I picked positive/negative skewed.

But the answers said it was symmetrical, so anyway I assumed that the symmetry thing was only approximate, but then there's another example, it was slightly skewed, but you could kind of guess they meant it to be symmetrical, and the answers said bloody skewed.

If this turns up in my half yearly this week i wont have any idea what to say.


If there was a graph that was almost symmetrical, but was slightly skewed, what should I do?

Thanks

I think symmetrical means symmetrical. Exactly symmetrical.

If it's not symmetrical then it must be skewed in some direction.

So if it's almost symmetrical then you can say that it's almost symmetrical and very slightly skewed in a positive direction (if that's the case).

Yeah that would probably work, thanks.

But what if there is a multiple choice on it?

 

[PC]

Choices would be something like
(A) Positively Skewed
(B) Negatively Skewed
(C) Symmetrical
(D) Bimodal (or some other stupid word)

So if it's not exactly symmetrical, it would have to be A or B depending on the example.

ok thanks

What? You have multiple choice in your exam paper! Poor u
