My bio teacher is basically a dumbass. He doesn't teach us anything (literally) and gives us a test. Just yesterday we had to do a lab for him and we had no outline, (just said look at your handout, and I see that I have 20, with a rat on it and showing me how to make a graph on excel, real useful if I don't know what I'm doing).
But that aside, I don't understand the student's t test. What is the point of it? I have all the equations memorized for things like standard deviation, standard error, freedom (lol), variance, etc. How the hell do I make one? I'm looking at the sheet and I'm basically just going wtf. Like I just want a basic run down of it. I found out how to find the valus on my graphing calculator. That's nifty and all, but I don't understand how on the sheet, there are different values for each df. All I got was one df and on p, and we're probably going to have to make a t tailed table on tomorrow's test.
