"NettetNow, drag the formula to cell B7. In cell B2, we have the normal distribution for the chosen data. To make a normal distribution graph, go to the “Insert” tab, and in “Charts,” select a “Scatter” chart with smoothed lines and markers. When we insert the chart, we see that our bell curve or normal distribution graph is created. " - Linear distribution curve
