AI Thread Summary
The discussion focuses on a human factors major seeking guidance on statistical analysis for a thesis involving noise levels from three vehicles. The goal is to determine if the average decibel levels from five individuals per vehicle indicate that the vehicles operate at similar noise levels. The user acknowledges a lack of strong statistical background and requests assistance in proving that the data sets belong to the same population. The forum moderator emphasizes the importance of posting in the appropriate subforum to avoid redundancy. Overall, the user is looking for help with statistical methods to analyze their noise data effectively.

So here's the deal. I'm a human factors major and because I had a single stats class I am required to have a statistical analysis in my thesis. With that said it was a few years ago and wasn't my strong suit anyway. Here is what I am trying to do.
I have taken noise samples from three vehicles to determine how much noise the crew members are subject to while operating. I have average decibel levels for five individuals per vehicle. My goal is prove that the data sets are all from the same population which I believe would mean the vehicles operate at approx the same noise level.
Any help is appreciated. Thanks.

Hello and welcome to MHB! (Star)

I have deleted the duplicate thread posted in our Pre-University "Basic Probability and Statistics" subforum, as I feel you will get more appropriate help here.

We do ask that a thread be posted only once in the most appropriate area to avoid redundancy and potential duplication of effort on the part of our helpers, whose time is very valuable. (Smile)
 
Thanks. I figured that would happen. I didn't see this group until I posted in the other one.
 

Thread 'Deductive proof in logic formal systems'

I was reading documentation about the soundness and completeness of logic formal systems. Consider the following $$\vdash_S \phi$$ where ##S## is the proof-system making part the formal system and ##\phi## is a wff (well formed formula) of the formal language. Note the blank on left of the turnstile symbol ##\vdash_S##, as far as I can tell it actually represents the empty set. So what does it mean ? I guess it actually means ##\phi## is a theorem of the formal system, i.e. there is a...
