My analytical chem lab frustrates me.<\/p>\n
We get marks for accuracy and precision, and despite my best efforts, I have FAILED this criterion in more than half of my labs. Each time with a 9\/20. It’s some kind of curse, I swear. I’m always accurate–always–but my precision could use a little work. It’s getting to the point where it’s a bit ridiculous, really. In this last lab, I had a 99.42% correlation between my data and the best fit line. That was worth a big, fat zero. (My Ka<\/sub> value earned me a 9.)<\/p>\n My accuracy and precision grades are worth 12% of my lab mark, which is ultimately 3% of my overall mark in the course, but keep in mind: I have to pass the lab to pass the course. =_=<\/p>\n I mean, in one lab my prof couldn’t even TELL me what went wrong. v_v And the other one didn’t count, and I overshot my first titration, so I really didn’t care. ARRGH. I have two labs left to make this up, and … yeah.<\/p>\n I’m NOT a bad chemist otherwise in that lab; it’s not like the rest of my accuracy\/precision grades are marginal pass marks. The other ones (if I remember correctly) are something like 16, 19, and 17.5. I mean… if my marks were consistently low there would be a problem, but since they’re not, I just really can’t understand what’s going on.<\/p>\n Well, scratch analytical chemistry off my specializations list. :tongue:<\/p>\n","protected":false},"excerpt":{"rendered":" My analytical chem lab frustrates me.
