SUMMARY

The discussion centers on determining the statistical significance of a 6.03% increase in particle counts from 232 to 246, with associated errors of approximately 15 and 16, respectively. The participant, Max, seeks clarity on whether this increase is statistically insignificant, given the error margins that result in a combined error of ±9.72%. The conversation emphasizes the importance of defining "statistically insignificant" and suggests that further statistical analysis may be necessary to draw definitive conclusions.

PREREQUISITES
  • Understanding of basic statistical concepts, including error propagation.
  • Familiarity with particle counting methodologies.
  • Knowledge of statistical significance testing.
  • Experience with data analysis software, such as R or Python for statistical computations.
NEXT STEPS
  • Research the concept of error propagation in experimental data.
  • Learn about statistical significance testing methods, including p-values and confidence intervals.

Hi guys,

I have a very easy question to ask - been bugging me for a while but I keep
forgetting to ask it!
So I am doing a particle counting experiment at the moment and changing the
conditions slightly each time to see if there is an increase in the number of counts
(there should be, I'm trying to show that with the level of statistics I have it is
undetectable though). My question is an extremely simple one about errors in the
increase of counts.
Say I count 232 particles (giving me an error of approx. 15) and then alter the conditions
and count 246 particles (giving me an error of approx. 16). Then the percentage increase
in counts is (6.03 ± 9.72)% (adding the errors in quadrature). My question is, is this enough
to say that the increase in counts is statistically insignificant? Or do I need some other sort of argument?

Cheers,
Max

You'd have to precisely define statistically insignificant.
