13 Experiment 1 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 -3 -4 10 11 24 20 30 37 47 x 100 115 120 122 129 133 140 141 150 151 154 157 160 170 172 183 y 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 preferred graph paper showing the errors in terms of error bars. (b) Calculate the slope and intercept of the best fit graph .Draw the best fit graph on the above graph. 2. The expression of refractive index of a prism id given by the following relation: ) 2 / A sin( 2 D A sin ± ² ³ ´ µ + = . Assuming the error of A and D as ± A and ± D, express the error of . Here ‘A’ is the angle of the prism and ‘D’ is the angle of deviation. 3. The relation between two independent variables X and Y is given as the empirical expression Y = a X + b X 3 .The experimental data for X and Y are given below :
