I think it’s easy to put up information in a PowerPoint presentation. All you need to do is put in all the data and analysis you did. Then, arrange them such that they are both aesthetically pleasing and understandable.
However, it takes domain knowledge to actually make sense of them and present them such that you add a story to it and make the analysis come to life.
Presenting information is relatively easy compared with presenting ideas you gleaned from the insights you unburied.
