DC Racoon's Statistical Journey with Excel

Microsoft Excel is a fantastic and useful tool for a range of purposes. You can use it as a spreadsheet, for project tracking,  data graphing,  or as a visualisation tool. You can pull data from files, websites, or databases. Data can be sliced, spliced and analysed. You can build static and  dynamic  dashboards with graphs, and publish them to the Internet. You can automate repeated tasks and write scripts for custom tasks. Recently I had the time and the opportunity to learn Excel's statistical sample testing functions.

For management, a diagram implies you have a clear idea on how it should be implemented. For the engineers, while visually accurate, the document but still difficult to read. Improvement to the table Recently, I was reviewing another data centre's structured cabling design. They grouped the ports by slots; example Ports 1-12 = Slot 1, Ports 13-24 = Slot 2, etc. So when it came to my design, I used the same idea. Removing clutter in your table makes it easier to read. This wasn't a major improvement, but the slots gave me the next idea. Visu
