Why Is My Gradient Too Small in the Young's Modulus Experiment?

[DrMouze]

I was doing an experiment on Youngs Modulus, the set up is a steel bar fixed on both ends an a mass put on the centre. Measuring the depression and then drawing a graph of depression vs mass. then using the gradient of to get Youngs Modulus. And my peoblem is the gradient is hust too small, yet according to my practical manual is suppossed to give me the correct answer, pliz help is it possible ? Because i just can't seem to get it
