How to write a conclusion
The conclusion of an assay, a dissertation or a thesis is a summary of the entire story that you have written. The conclusion is supposed to conclude the entire document in either a few pages or paragraphs depending on what is being written. Both the introduction and the conclusion are important elements of a document. These 2 parts are usually read first by most people and hence decide if they want to continue further with the whole document or not. You will be surprised how many people read the conclusion first of a thesis, assay or a story.
If it's a story or an assay, then conclusion should be about a paragraph long with a few sentences ideally 3 or 4 consisting of review of the important points. Although there is no set way for writing a good conclusion certain rules must be followed. For example, the conclusion should tell the audience why the document is important and a summary of the findings.
For instance, if an assay has been written on
"Atherosclerosis and coronary heart disease (CHD) and its risk factors"; a good conclusion could be somewhat like this;
Atherosclerosis is a disease of the arteries resulting in coronary heart diseases. It is a major killer in the developing world with increasing numbers in the developing world. Its major risk factors include, smoking, high fat diet, genetic predisposition and unhealthy life style. This can be reversed by patient education and awareness and effective health management.
The above is an example of how to write a good conclusion. In the above example; the assay would have dealt with disease, its pathogenesis and discussion on its risk factors. In 3 or 4 sentences we have described what CHD and the major risk factors. The last sentence is even trying to suggest a way to improve the situation.
Think of a conclusion as the closing paragraph and do not end with few wild statements and do not end abruptly. Try to draw a conclusion out of it.
