Experimental Design B/C

[Phys1cs]

Do we have to show example calculations for coefficient of determination values, if added? I use my calculator for those as well.

your r or r^2?

I never have. Those are also calculator based things (I have no idea how you could calculate that...)

No no no no no no no
No.
You show your calculations when you calculate your averages for the quantitative data table

You have to show more than just the calculations for averages.

To the rubric.

h. Quantitative Data - Data Table (12 points)
_____ All raw data is given
_____ All data has units
_____ Condensed table with most important data
included
_____ Table(s) labeled properly
_____ Example calculations are given
_____ All data reported using correct figures (significant
figures C Division only)

See "Example calculations are given". That refers to the condensed table with the most important data (the averages). And now, just to take it a step forward.

j. Statistics Division B&C– (4 points)
_____ Average (mean), median, mode, range, or drawn
in line best of-fit
Division C only (6 additional points)
_____ Measure of central tendency
_____ Measure of variation
_____ Other appropriate statistic used

Nowhere does it ask for sample calculations

Okay. So the very least you have to do is show example calculations of the averages. There still is nothing wrong with including anything else, and you still wouldn't have any need to show the calculations for either the line of best fit or for the r value

For a line graph, do you have to graph all trials and the averages, or just averages?

[Phys1cs]

For a line graph, do you have to graph all trials and the averages, or just averages?

line graph: trials
bar graph: averages

this lets you draw in your line of best fit with a line graph, which is generated from your trial points. Bar graphs should have only one bar per IV, so graph the averages

I'm just wondering how people are preparing for this event because it seems as if my group and I aren't preparing "correctly". People have given us materials, and our goal would be to come up with an experiment, perform the experiment, and write the experiment in the 50 minutes. Are we preparing correctly? Should we get someone to give us a specific topic question and work from there?

Is someone looking at your lab? You should get someone (teacher, or someone else familiar with a lab) to "grade" it on the official rubric so you know what you are consistently forgetting/missing. Add in a topic question, because you always get one at the competitions, so it's much closer to replicating the competition itself.

Yes, we have been receiving feedback. We were just unsure if we were supposed to receive topic questions because from past experience, we were never given a topic question and were simply told to create a random experiment with the materials that were given, but thank you for the suggestions!
