MHB Need assistance to decide with analysis to use for problem

AI Thread Summary
The discussion focuses on analyzing how construction stilts influence walking patterns based on user experience. The researcher has two groups: expert and novice stilt users, and plans to compare their walking parameters both with and without stilts. An independent t-test was initially considered for analysis, but it was pointed out that there are actually four samples due to the two parameters of expertise and walking condition. Therefore, a more suitable statistical method, ANOVA, is recommended for this analysis. Using ANOVA will allow for a comprehensive comparison across all groups and conditions.

I am interested in examining how construction stilts affect walking patterns, and how experience with the stilts affects walking patterns. I recruited a group of expert construction stilt users, and a group of novice users and videoed their both walking on stilts and without stilts. I want to see if there is a difference in walking parameters between groups and between the walking conditions.

I am considering using an independent t-test for two samples. Is this the correct approach?

Thanks,

Dants

Hi Dants, welcome to MHB!

A 2-sample t-test is to test if the means of 2 samples are different.
However, it appears you have 2 x 2 = 4 samples.
That is because you have 2 parameters: construction and expertise.
In such a case we need a more general method that can be applied to more than 2 samples: ANOVA.
 

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...
