- Suggest a hypothesis that explains the pattern/shape for the trend of the data in my graphIs there a reason those sig figs are wrong or are my calculations just completely off?Hi! I m working on a lab right now. I have three measurements, 1.057 .9442 .9629 and a mean measurement of .9880. Im supposed to find the deviation and I understand that i just find the difference, but can a deviation be negative?
