Re: Experimental Design B/C
Our teams have been having trouble getting points for "Example calculations given" under Quantitative Data because our dependent variable might be time, or something that doesn't require calculation. Are we supposed to put averages? We don't put the averages in the table, because we leave those in the Statistics portion of the experiment.

Re: Experimental Design B/C
We always did sample calculations for the Statistics portion. With the raw data table there normally isn't much to put calculations for besides average. Do include average in you sample calculations as well as any used in the experiment/the statistics portion.chscioly wrote:Our teams have been having trouble getting points for "Example calculations given" under Quantitative Data because our dependent variable might be time, or something that doesn't require calculation.

Re: Experimental Design B/C
My best advice is to not let the word "sample" deceive you- to get full points, you often have to show all your work. This includes the formula you are using and any calculations needed to construct your summary/second table.Panda Weasley wrote:We always did sample calculations for the Statistics portion.

If our experiment dictates that we need to use the raw data to calculate another number (i.e. using frequency to calculate period), my team draws a second table to list the calculated data. In this case, our sample calculations are the formula needed for the calculations (T=f^-1) and every individual calculation.
Otherwise, the summary table lists the averages for each level of the IV. We write out the formula for calculating the average and, once again, show the calculation for each data point.

Re: Experimental Design B/C
Ayo, just a quick question - what should a "condensed data table with most important information" look like? We already have a table for all results from all trials, so should the "condensed" table simply be one with averages?

Re: Experimental Design B/C
The condensed table should just be the averages of your trials. Make sure you keep it separate from the main table, and also include sample calculations. If you do it wrong it's an easy way to lose a few points.nghtlrk wrote:Ayo, just a quick question - what should a "condensed data table with most important information" look like?

Re: Experimental Design B/C
An addition to what I said earlier: if you have to calculate some data (like period from frequency), make a second table with that data, THEN make the table of averages with that.maxxxxx wrote:The condensed table should just be the averages of your trials.

Re: Experimental Design B/C
On the rubric, under procedures, what do they mean by "repeated trials"? Like how would you include that in the procedure?

Re: Experimental Design B/C
After explaining how to do a trial, say "repeat steps x-y with (insert level of IV)". I don't do procedure so that may not be as technical as they want it to be.Eureka314 wrote:On the rubric, under procedures, what do they mean by "repeated trials"? Like how would you include that in the procedure?

That's pretty much it. Make sure that you say repeat.maxxxxx wrote:After explaining how to do a trial, say "repeat steps x-y with (insert level of IV)".
