In my research I was asked to edit some conclusions making them more significant at the behest of my adviser. I did what I was asked because I was immature at that time in my thesis work. At that time I didn't know its was wrong.
These changes can't effect the anyone because I only changed the "p value" of the result. I changed a little in an "ANOVA table" for some result significance. If I put all results without change the "p value", the thesis can also be approved at that time. This all happened because of less knowledge of my adviser on how to tell me to change some results, which now I understand after my work and experience in teaching, but I inserted all the experimental data accurately in my thesis.
If someone checks my experiment data in "ANOVA" they can find the change in the "ANOVA table" (my mistake). Now I am worring about my thesis and Master degree. If someone complains in future about my thesis, will the University revoke my degree and how I can defend my degree? I worked on machining of some material in my thesis. Can I do something now to correct my thesis?
