Yes. As a scientist it is your job to present your results in a clear way so that anyone reading your work can draw the same conclusions that you did. In order for someone to decide whether your results are valid or not, they will need to know exactly how you came to your conclusions. The more details you can include, the better. This can be presented clearly in a table or graph.
