I really need some help with the following task:

1. This is how the data looks like

id -- param1 -- param2 -- param3 -- param4 -- param5
1 -- 4.50628 -- 4.15675 -- 4.50154 -- 4.68885 -- 4.26521
1 -- 5.06993 -- 4.17074 -- 4.56363 -- 4.86102 -- 4.05149
1 -- 4.58889 -- 4.08346 -- 4.18945 -- 4.5038 -- 4.46064
1 -- 4.95584 -- 4.11911 -- 4.39647 -- 4.78431 -- 4.16094
1 -- 4.9744 -- 4.26242 -- 4.34986 -- 4.84562 -- 4.55548

3 -- 4.57822 -- 2.91735 -- 4.92302 -- 4.32555 -- 5.3558
3 -- 4.58379 -- 3.42438 -- 4.42503 -- 4.48771 -- 4.84775
3 -- 4.40123 -- 3.62117 -- 4.35071 -- 4.66773 -- 5.27611
3 -- 4.28061 -- 3.27324 -- 4.32394 -- 4.50685 -- 5.12873
3 -- 4.54213 -- 3.20065 -- 4.49449 -- 4.33592 -- 5.05669
3 -- 5.00828 -- 3.61886 -- 4.93453 -- 4.88741 -- 5.32345

13 -- 5.3247 -- 4.19645 -- 4.92201 -- 4.75864 -- 4.94418
13 -- 5.08517 -- 4.46726 -- 4.85311 -- 5.05022 -- 4.52623
13 -- 5.30472 -- 3.87078 -- 4.72273 -- 4.72508 -- 4.82793
13 -- 4.68255 -- 4.0309 -- 4.36258 -- 4.96804 -- 4.20429
13 -- 3.82007 -- 3.60482 -- 3.98303 -- 3.7635 -- 4.23959
13 -- 4.65918 -- 3.58418 -- 4.48422 -- 4.75422 -- 5.02989
13 -- 4.57815 -- 4.04331 -- 4.69041 -- 4.35187 -- 4.75985
13 -- 4.98419 -- 4.30742 -- 4.6936 -- 4.94204 -- 4.62063
13 -- 4.84269 -- 3.58674 -- 4.283 -- 4.83578 -- 4.70742
13 -- 5.29344 -- 3.51773 -- 5.24251 -- 4.81079 -- 4.82505
13 -- 4.53487 -- 3.85768 -- 4.47558 -- 4.78298 -- 4.7784
13 -- 4.77014 -- 3.91667 -- 4.48578 -- 4.84291 -- 4.96956
13 -- 4.92411 -- 3.84995 -- 4.64165 -- 4.91415 -- 4.64633
...

2. Each block of params under the same id is viewed as a separate sample

3. I need to understand whether the numbers in each such block are "close" (ideally the variance should be minimal). The combination of the params should be taken into account.

I was trying to create "random" samples of the same data (randomly choose numbers from unique blocks). And compare the mean variance of those samples with the mean variance of initial samples. But I am an absolute dummy in statistics and will appreciate any help with the task!

Thanks a lot in advance.

Welcome to TFS.

We don't do homework for each other.. we pass or fail on our own merits here.

That's not a "homework". It's a part of my research and I just need some help with statistics. Thank you anyway for the reply.

what is the correlation between these numbers?

id 1, yes they are close withonly a small variation
id 3, no the variation is a larger percentage of the number
id 13 either yes or no depending on the requirements of the definition of close, but the variation is not that big so more likely yes

plot the numbers on a mathematical graphing (funtions) program like graphmatica, and look at the variation in the line compared to the overal hieght of the line

Who is letting you do research without knowing the first thing about statistical analysis?

This is basic, basic, "Statistics 101" stuff. Pick up a stats book.
