Ok guys, I'm pretty pissed off as I have no fucking clue what kind of statistical test. As tl.net has been so helpful so far, lemme see if I can ask this and have some statistic/math major/ anyone who knows some math, answer my blog.

So, I have 3 animals that I am testing a certain "characteristic" in. I have 3 trials for each of the "characteristic", which results in a number. I am also testing the animal's change in the "characteristic" under 4 different "conditions".

I tested my experiment, 36 different numbers, all organized in a chart. Now, I want to prove that the means of the numbers are statistically significant, and hopefully also mix in some stuff about the variance of the data.

Comments are appreciated. Answers or suggestions to the question are greatly appreciated. Detailed answers or step-by-step methods of how to do it are like "Ok,, how much money do you want me to mail to you" style appreciation.

kkthx.

Since you are comparing averages (I'm assuming you're putting averaging the trials for each animal first), you should probably use a 3-way ANOVA. Google how to do it via excel.

Yeah, I planned to use an ANOVA test, but the only problem is, the variances of the population is different. It's been a while since I took stats, but if my sample population variance is different, can I still assume the population variance is the same? fyi, I have the same sample size for each different condition. Another question I have is in terms of the number of samples (n). Since I'm doing 3 trials per animal, should I average the three trials and count my n = 3? Or should I count the all the trials as separate "n"s. The first one doesn't let me assume normality of the sample (do I need to do this for normality?) because n < 30 so the central limit theorem doesn't apply. On the other hand, the second way lets me get closer to asuming normality, but seems to break one of the assumptions in an ANOVA test, the independence in the selection of data.

What a misleading thread title. I hope you fail. + Show Spoiler +

Well I don't, but if it's math help please indicate that -_-a
