Experimental Design B/C

Hmm alright...I'm going to try to find that post.

Also when listing materials do you list pencil/paper? If you're only using them to write with?
Also if you were bouncing a ball on the table/ground, would that be listed as a material.

Paper and pencil, no, because that isn't used in your lab, it's used in the write up, which has (in a sense) nothing to do with the lab you are conducting. Your only materials are those you use to perform the lab, not to complete the event.

If using a table, or the ground, I would opt for a table. Table you can list the type of material, or just generally describe the surface (lab table, wooden table, etc), while ground is just...ground. I wouldn't list the ground in the materials, but would list the table. Tables can be different and changed, while again, the ground just....is. Though the part about the ground is just me going out on a limb. I could be totally incorrect

By ground Asteroidea probably meant floor, because it is unlikely that they would hold Exp. Design outside. In that case there are different types of floors: wood, tile, etc. So you could argue that it should be in the materials. I actually don't think either the floor or the table should be included as a material, but that's just opinion and I have no argument, it's just a gut feeling.

Really, I think that you should ask the event supervisors. That's always the safest option.

Just something to note, my team has had multiple adults try and grade our papers from the rubric. In none of our experiments did we include the floor or table as a material. None of the graders, as far as I know, commented on it.

Traditionally we never listed paper/pencil...until we got points taken off.

you got points off for not putting paper and pencil? Those aren't part of the lab, so you shouldn't be including them... unless you were using them in your experiment

If you aren't using your paper and pencil for an experiment, don't put it for materials, and get counted off points, the event supervisors have no idea what they're doing.

I guess that's why I have issues with this events...the way event supervisors grade this differs so much each time. For example my partner once got 0 points on the entire stats section even though all the work was there and clearly marked. Or another time on section h (which is worth 12 pts total), my partner only received 5 pts because there are 6 "parts" on section h and he missed two points, and instead they just counted up the 5 "parts" he did get right and didn't double for the correct score. Also more of a relevant question, for your dot plots do you always graph a linear line of best fit?

Yes, it's a good idea too. That way in your stats you can mark slope, equations, and use that as part of your analysis. Drawing them in is also good, it gives the grader the evidence that you know how to plot a graph, but can also analyze it or what not that they look for with this stuff

[Asteroidea]

Right but my question deals with more of what if you get a plot that looks exponential? Should you graph it as an exponential line or linear? I guess in that question the emphasis should have been on the word linear.

[ThatRoboGuy]

Plot it exponentially.
Think of what a grader would see; a plot of data that seems to have a curve, though the line of best fit is linear.
