For the other measure of central tendency, Standard Deviation and the Variance (because you need the variance for standard deviation) are common. Those are what I use, because Standard deviation is used to find the general range the data should be falling in.jwalkotten wrote:A couple questions if anyone could help

1) it says to give a measure of central tendency (for division C). What does it want here? Because mean, median, and mode, are all measures of central tendency, but we have already given these...

2) what does "other appropriate statistic used" mean? some people have said to get a regression analysis, but how do you get that for all three levels of IV? because your regression analysis is going to be for the line of best fit for your data, but your statistics are supposed to be comparing each of you trials in each level of IV (at least that's what I thought...)

Thanks if anyone could help!

Regression Analyses are more interpreting your regression, or line of best fit.
