My task was to determine the focal distance and the magnification of a converging lens. I've done everything as stated in the procedure. The problem that i have is that when i am calculating the magnification in two differents ways i.e M1=b/a and M2=h'/h where a=distance form object to mirror, b=distance from image to mirror, h=height of the objet and h' height of the image, those two magnifications are very divergent. for example in 5 trials if i choose two : M1= 2 while M2=0.95

M1=1.57 while M2=0.85

...

So how can i explain it? Can you give me a hint or just some error analysis methods (link if possible)? Cause i've never get a course about how to analyse errors.
