On the graph, the vertex is where the bottom of the U is. In general, it's always that same place on the U, but the U could be turned upside down or left or right.

Hope this helps!
We have been given that the standard deviation of a group of 20 scores is 15 and we are asked to find variance.

Therefore, our variance is 225.
