Not sure what to do with data
http://www.talkstats.com/showthread.php/56980-Not-sure-what-to-do-with-data?goto=newpost
Mon, 28 Jul 2014 20:09:33 GMTHello,

i spent a very long time gathering data and now i need to write a paper about it.
Unfortunately, i'm relatively new to statistical analysis.

I have
1. one big set of data: >5000 texts evaluated by 13 indices. It looks like that http://tinypic.com/r/4l263c/8
2. a smaller data set of different pieces of text (>1000) evaluated by the same 13 indices, that i need to compare to the first one.
3. The first one is also separated into smaller sets by category of text. I might need to compare them to each other.

There are no hypotheses and, at first glance, there are no visible trends. But a paper needs to be written.

I would be very grateful for any kind of helpful suggestion on what test/analysis to do.

There are large events taking place on park land.
We are using noise disturbance hardware to measure decibels during and not during events.
We have >1000 samples for our control and our experimental.
The data is not normally distributed.
The variances are different.

What test do I use to see if there is a difference between means?

I keep coming to the Mann Whitney test, but I can't find any tutorials on how to perform this test with large sample sizes.

Any suggestions?
