When writing the conclusion part of your abstract, remember that these conclusions should be precise and concise. There is no need to re-summarise what you have already discussed or the contents of your dissertation. This is an informative abstract, not a descriptive one. If you are unsure of the difference, you may find the section, Choosing between dissertation abstract styles: Descriptive and informative , helpful. Furthermore, be careful not to make claims that cannot be supported by your findings. There is always a danger to over-exaggerate and/or over-generalise in this part of the abstract, which should be avoided. It is unlikely that you will have changed the world through your study, but you may still have added something significant to the literature, so try and strike the right balance.
