Question about error analysis and chi

What is "chi" ? I was looking at the physics AAMC topics list and I was wondering if someone could tell me what that is? Thanks!

I'm pretty sure Chi is a type of statistical analysis... But I'm used to seening it called Chi-Squared. Hope that helped. Good luck. 🙂

Chi is the magnetic flux..

Thanks everyone,
would the passage define more in terms of what it is, or should I have a general understanding of how to apply it in error analysis?

Just briefly touch up on it... I dont remember where I saw it, but I did..

Haha, I haven't seen anything on the MCAT that would even remotely require you to use chi square analysis.

basically lets say you wanted to see whether two genes are linked or not. we know a hybrid cross (Aa x Aa) of unlinked genes will give a 1:2:1 ratio. What if the numbers were 23:39:19. You would need to use the chi^2 equation and compare the value to a table to figure out your p value and determine from the null hypothesis whether it is linked or not... way beyond the score of the MCAT!

Not on the MCAT. Don't worry about it.
