What do ya think?

OpenStudy (anonymous):

This graph is incredibly nonsensical for one reason alone :P

OpenStudy (snowfire):

Is it what I'm thinking too? That the scale needs some work? And that there are so few data points?

OpenStudy (anonymous):

@QueenBee232 's right

OpenStudy (snowfire):

Yeah that would do it, I thought I just wasn't seeing the relationship between the two variables. But connecting them with lines leads the viewer to believe that there should be some connection between all the points, like I previously thought.

OpenStudy (anonymous):

The scale is weird, and there aren't many data points, true: but connecting them implies that there is some correlation between the points, which there is not. They each have different amplitudes that the graph doesn't take into account, so they shouldn't be connected by a line.

OpenStudy (anonymous):

yah - it's really hard to read :P

OpenStudy (snowfire):

The fact that I second-guessed myself with the correlation aspect means it must be the lines connecting the points that is misleading.

OpenStudy (anonymous):

The scales are kinda weird, but at least they make sense! ^_^

OpenStudy (anonymous):

@QueenBee232 yup yup ^_^

OpenStudy (snowfire):

It's the only thing I can think of

OpenStudy (anonymous):

Hooray for ambiguous multiple choice questions! ^_^

OpenStudy (snowfire):

Hooray for aggravatingly misleading questions asking for why it is misleading!

OpenStudy (anonymous):

Not a bit ^^

OpenStudy (anonymous):

I think you're right, since a change in the mass has no effect on the period.

OpenStudy (snowfire):

Since changing the mass doesn't have any effect on the period, you would be right.

OpenStudy (snowfire):

Well, I mean the second choice.

OpenStudy (anonymous):

That's the third one methinks - the first is just pushed way up

OpenStudy (snowfire):

Oh yeah derp, third it is then.

OpenStudy (anonymous):

Whatchyou think?

OpenStudy (snowfire):

Since this graph compares the square of velocity and height, and the slope is positive, what can you say about it?

OpenStudy (anonymous):

Remember that the y coordinate isn't just velocity, it's the square of the velocity

OpenStudy (anonymous):

The y axis is still directly proportional to the x axis - just be mindful of what the y axis and the x axis represent.

OpenStudy (anonymous):

You tell us! ^_^

OpenStudy (snowfire):

We can't tell you everything, although we sorta already did ^^

OpenStudy (anonymous):

winner ^_^

OpenStudy (anonymous):

thnx
