Error Analysis and Graph Drawing Assignments
1. Experimental data (in arbitrary units) of some experiment is given below:
x-10 4 10 16 20 35 40 32 40 45 53 60 65 70 80 85
y-17-20-30-17-35-2-19 -34 10 11 24 20 30 37 47
100 115 120 122 129 133 140 141
150 151 154 157 160 170 172 183
7 50 80 77 79 80 83 80 100 90 113 102 110 100 106 101 200

(a) Assuming 10% of error in Y values, plot the data on the provided graph paper showing
the errors in terms of error bars.

(b) Draw the best fit graph on the above graph. Calculate the slope and intercept of the best
fit graph.
