About creating and reporting "good" tables:
It's also helpful in a table to have a minimum of four significant digits. A good choice is often to use the default provided by whatever software you have used to fit the model. Software designers have chosen their defaults for a good reason, and I'd go with that. Unnecessary rounding is risky; who knows what information might be lost in the foolish pursuit of a "clean"-looking table?About creating and reporting "good" graphs:
If you must make a graph, try only to graph unadorned raw data, so that you are not implying you have anything you do not. And I recommend using Excel, which has some really nice defaults as well as options such as those 3-D colored bar charts. If you are going to have a graph, you might as well make it pretty. I recommend a separate color for each bar—and if you want to throw in a line as well, use a separate y-axis on the right side of the graph.Note: please do not follow these instructions for creating tables and graphs! Remember, this is an April Fool's Day prank!
