• How do you ensure you are looking at the data the right way and preventing errors in your spreadsheet?

You should look for outside resources to help you understand this better and to present a convincing position that you and your fellow students will find ueful in the future. Avoid taking the first few items on a Google search and do some real investigationwhich is not the same as spending hours. Look for responses from reputable business sources such as magazines like Inc., Forbes, Harvard Business, etc. Or use the library links to find academic journals. You could also look in LinkedIn Learning or even find solid info from YouTube.
