Normal distribution, degrees of freedom, etc etc my brain is blue screening. How am I supposed to remember all this shit? HELP.
I'm bombarded with like 12 new complex terms in each lecture that I'm supposed to just fully understand. Gdhsjfbe fuck my ADHD brain.
This isn't a universal definition of degrees of freedom, it's just "degrees of freedom as it applies in an undergraduate level stats course," which is typically for the t distribution. It's n-1 because you assume all your observations are independent of one another. In other contexts (ANOVA, e.g.), the calculation is different.
I get that, just thought it was a strange definition given what degrees of freedom actually refers to
