Question

I like the discussion on variability. When we work on an experiment in chemistry lab, people get different results for the same experiment. What gives rise to variation?

Answer 1

In a chemistry lab the variation must be coming from things like differences in measurements, maybe spilling, not observing readings correctly, things like that. Some can be corrected for. Like a balance that is constantly off by a small amount. But some cant. Like what if the wind blew some of your sample away.
