 Statistics and Excel. Standard deviation and variance for a population. Calories data. Get ready, taking a deep breath, holding it in for 10 seconds, looking forward to a smooth soothing Excel. Here we are in Excel. If you don't have access to this workbook, that's okay because we'll basically build this from a blank worksheet. But if you do have access, three tabs down below, example, practice, blank, example, in essence, answer key, practice tab, having pre-formatted cells so you can get right to the heart of the practice problem. Blank tab, blank worksheet, but with just our data in it so we can practice formatting the cells within Excel as we work through the practice problem. If you don't have access to this data, it's a pretty long data set so it would be difficult to simply type it in there. You can look at online resources for sample data sets such as Kaggle.com, K-A-G-G-L.
