 Statistics and Excel. Bell curve. Test score example, part number three. Get ready, taking a deep breath, holding it in for ten 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 basically built this from a blank worksheet. However, we started in a prior presentation, so you might want to go back there if you want to start with a blank worksheet. But if you do have access to this workbook, there's three tabs down below. Example, practice of blank. Example, in essence, answer key, practice tab, having pre-format of cells, so you can get to the heart of the practice problem. Blank tab is where we started with a blank worksheet and are continuing at this point in time. Quick recap of what we have done thus far. We've been creating our bell curve or normal distribution and we're not stopping building the bell curve yet. Why?
