TA marking a06: Daoyan Wang perfect marks: 5 5 5 5 5 8 ============================================================= correct one: p0 = 0.0542269 +/- 0.006935 (12.79%) p1 = 0.100866 +/- 0.0008351 (0.828%) chi^2/dof = 0.0495923 First typical mistake (unweighted fit): p0 = 0.0564751 +/- 0.01214 (21.49%) p1 = 0.10036 +/- 0.001054 (1.05%) Second typical mistake is to write down chi^2 instead of chi^2/dof. [Actually one should always show BOTH, since "standard deviation" is larger for the same chi^2/dof when there are more dof. - Jess] Third is typing in data rather than loading from file. Fourth is, *DO NOT FORGET TO INCLUDE SOURCE CODE*. This time I didn't really penalize this. Next time I will. Another issue is that I can not open some pdf's. Well, it is possible that your pdf was not produced correctly (so, when doing next assignment, do not forget to check whether they can be opened). Another possibility is that the software in my computer is not powerful enough to open them. If you suspect this is the case, pls let me (Daoyan Wang) know during the tutorials. Let's try to open them together. ============================================================== Rubric : if not weighted fitting (or forget to write p1, p0) -1.5 forget to write down variations of p1, p0 -0.5 forget to write down chi^2 -0.5 forget to write down p1, p0, chi^2 -2 not produce a graph properly (e.g., somebody used 'print screen') -0.5 any other minor mistake -0.5 any other major mistake -1 ---------- above for graphing, now for python --------------- five marks for calculating, three for plotting calculating if not report values of p1, p0, depends: 1) without plot: -1 (i.e., -1 for p0,p1. Of course another -3 for not plot) 2) with plot: no penalty Of course, if the code did not work at all, at most 3 marks for the whole problem. plot: same standard as all the plots above. typing in data rather than loading -2
