Hi, so I'm currently writing a lab report and need to determine the error in the value of my graphs gradient,

and I've found the mean gradient and its deviation (though this is little use)

The data in y is

11.39 ± 1.67

21.39 ± 2.29

33.06 ± 2.85

47.27 ± 3.40

56.25 ± 3.71

66.02 ± 4.02

(all in m

Thanks in advance!

*m*. I have found the maximum and minimum gradient from the 'worst' lines of fit but am lost where to go from there. My data analysis/statistics lecture notes are no help on this topic, neither is Google. It seems like it should be an easy topic!*m*= 11.20 m^{2}*m*= 9.79 m_{min}^{2}*m*= 12.06 m_{max}^{2}and I've found the mean gradient and its deviation (though this is little use)

*m*= (11.20 ± 1.14) m_{avg}^{2}The data in y is

11.39 ± 1.67

21.39 ± 2.29

33.06 ± 2.85

47.27 ± 3.40

56.25 ± 3.71

66.02 ± 4.02
