Data Parametric

AI Thread Summary

Parametric data assumes a normal distribution and is analyzed using statistical methods that rely on this assumption, such as t-tests and ANOVA. Non-parametric data does not assume a specific distribution and is analyzed using methods like the Mann-Whitney U test and Kruskal-Wallis test. The choice between parametric and non-parametric analysis depends on the data characteristics, including sample size and distribution. Parametric tests are generally more powerful when the assumptions are met, while non-parametric tests are more flexible for non-normal data. Understanding these differences is crucial for accurate data analysis in research.

I would suggest that you type out your attempt so our helpers can perhaps give you some guidance.

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...

Thread 'Onto set mapping is the surjective set mapping, and into injective?'

The textbook is being fine. I asked the forum for some introduction to topology, and decided to start with Simmon`s. This naive question is due to ignorance of the words into and onto, which I don't distinguish in Spanish. A quick browsing sugests I'm right.
