I analyze data, as a consultant, for companies making important business decisions. In order to get my point across, which of the following strategies would be the most effective?

1) Take a lot of pictures of things relating to the data and produce a presentation to the company.

2) Don't carry any data related documents, just use your very highly developed public speaking skills to present to the company

3) Use a spreadsheet to gather the data, then insert a color-coded chart into a presentation slide.

4) Write an essay and present the paper along with handouts to the company.
