SUMMARY

The discussion centers on a human factors major seeking statistical analysis methods for a thesis involving noise samples from three vehicles. The objective is to determine if the average decibel levels from five individuals per vehicle indicate that the vehicles operate at approximately the same noise level, suggesting they belong to the same population. The user requires guidance on appropriate statistical methods to analyze this data effectively.

PREREQUISITES
  • Understanding of basic statistical concepts, including population and sample.
  • Familiarity with hypothesis testing and significance levels.
  • Knowledge of analysis of variance (ANOVA) techniques.
  • Experience with statistical software such as SPSS or R for data analysis.
NEXT STEPS
  • Research the application of ANOVA for comparing means across multiple groups.
  • Learn how to conduct hypothesis testing to determine population similarities.
  • Explore the use of SPSS or R for performing statistical analyses on noise data.
  • Investigate the interpretation of p-values in the context of statistical significance.
USEFUL FOR

This discussion is beneficial for human factors researchers, students in statistics, and anyone involved in analyzing environmental noise data for operational assessments.

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.
