plot whatever type of line it looks like. If you have a ti 93-94 or higher there are tons of types of regressions you can do. Choose the one that applies the most

I hope this isn't a stupid question... I apologize if it is, I know how frustrating it is to write answers to questions that should be painfully obvious.

In section h of the rubric, it asks for a "Condensed table with most important data included". My team interprets this as a smaller table, separate from the main one with only one column. In this smaller table, they put the average for each level of the independent variable. To me, this seems like extra work for no reason, especially since they specifically ask for the mean of each level in the statistics section.

Is this an accurate way of interpreting the rubric? I've gone through several practice sessions with my team in which I write the data this way, so I can do it if that's what they want. If possible though, I'd love to skip writing unnecessary stuff whenever possible.

Thanks.

Yeah, that's what you're supposed to do.
It's redundant, but it provides a quick reference to anyone who wants to see the mean and not all the data.

My partner just makes 3 different tables, one for each level of IV containing 3 trials with that IV, then puts the mean and standard deviation right underneath that...and then makes a condensed table

Is it best to make 3 different tables like that, or is it best to make one big table with all of your IV levels, trials, means, SDs together, and then make a condensed table by just cutting out the trials and SD columns/rows?

In the section for data table, we make two tables. One for all trials of all IVs, plus averages. Then our condensed table is just the averages of all IVs. Our statistics is a table with all IVs, and the mean, median, mode, SD, variance.... etc.

We make two tables, but they are different. One includes Stats, All levels of IV/trials, and then the condensed table with averages for each level.

Yeah...you should put the averages in both the statistics and your condensed table. Just a tip, I would label your condensed table condensed/summary table because I have seen two separate rubcrics, one which says condensed table and one that says summary table. We put both just in case.

How long does it take on average for your team to finish the procedure? Also, I have been having trouble with the analysis of data section. Any tips?

About 10-15 minutes for all of the procedures ^_^

Thanks ^_^ We take about half an hour for one nine-step procedure... .-. :oops:
