I have a lab and I'm having a hard time calculating or even understanding how to calculate the uncertainty. It wants me to calculate the uncertainty of temperature. Here is my data: time (mins) Temp (°C) 2 23.2 4 26 6 29 8 31.5 10 33.5 12 35.5 14 37.6 16 39.7 18 41.8 20 43.9 Don't I need some given value and divide the average by it? And I also don't understand how I'm suppose to calculate the uncertainty when the readings of the temperature was taken at different times... Help! Am I going crazy or did I do my lab wrong?
